Submodules

pyphyschemtools.Chem3D module

class pyphyschemtools.Chem3D.XYZData(symbols, positions)

Bases: object

Object containing molecular coordinates and symbols extracted by molView. Allows for geometric calculations without reloading data.

get_bounding_sphere(include_vdw=True, scale=1.0)

Calculates the center and radius of the bounding sphere using ASE. scale: multiplication factor (e.g., 0.6 to match a reduced CPK style).

get_cage_volume(grid_spacing=0.5, return_spheres=False)

Calculates the internal cavity volume of a molecular cage using CageCavityCalc.

This method interfaces with the CageCavityCalc library by generating a temporary PDB file of the current structure. It can also retrieve the coordinates of the ‘dummy atoms’ (points) that fill the detected void.

Parameters:

• grid_spacing (float, optional) – The resolution of the grid used for volume integration in Å. Smaller values provide higher precision (default: 0.5).

• return_spheres (bool, optional) – If True, returns both the volume and an ase.Atoms object containing the dummy atoms representing the cavity (default: False).

Returns:

• volume (float or None) – The calculated cavity volume in ų. Returns None if the calculation fails.

• cavity_atoms (ase.Atoms, optional) – Returned only if return_spheres is True. An ASE Atoms object representing the internal void space.

get_cavity_dimensions(cavity_atoms)

Calculates the principal dimensions (Length, Width, Height) of the cavity points.

This method uses Principal Component Analysis (PCA) to find the natural axes of the cavity, making it independent of the molecule’s orientation. Percentiles are used instead of absolute Max-Min to filter out potential outliers or ‘leaking’ points at the openings.

Parameters:

cavity_atoms (ase.Atoms) – The Atoms object containing the ‘dummy atoms’ generated by the cavity calculation.

Returns:

The dimensions (L, W, H) sorted from largest to smallest.

Return type:

tuple (float, float, float)

get_center_of_geometry()

Calculates the arithmetic mean of the atomic positions (Centroid).

get_center_of_mass()

class pyphyschemtools.Chem3D.molView(mol, source=None, style='bs', displayHbonds=True, cpk_scale=0.6, w=600, h=400, supercell=(1, 1, 1), display_now=True, detect_BondOrders=True, viewer=True, zoom=None)

Bases: object

Initializes a molecular/crystal viewer and coordinate extractor.

This class acts as a bridge between various molecular data sources and the py3Dmol interactive viewer. It can operate in ‘Full’ mode (display + analysis) or ‘Headless’ mode (analysis only) by toggling the viewer parameter.

The class automatically extracts geometric data into the self.data attribute (an XYZData object), allowing for volume, dimension, and cavity calculations.

Display molecular and crystal structures in py3Dmol from various sources:

• XYZ/PDB/CIF local files

• XYZ-format string

• PubChem CID

• ASE Atoms object

• COD ID

• RSCB PDB ID

Three visualization styles are available:

• ‘bs’ : ball-and-stick (default)

• ‘cpk’ : CPK space-filling spheres (with adjustable size)

• ‘cartoon’: protein backbone representation

Upon creation, an interactive 3D viewer is shown directly in a Jupyter notebook cell, unless the headless viewer parameter is set to False.

Parameters:

• mol (str or ase.Atoms) –

  The molecular structure to visualize.

  • If source=’file’, this should be a path to a structure file (XYZ, PDB, etc.)

  • If source=’mol’, this should be a string containing the structure (XYZ, PDB…)

  • If source=’cif’, this should be a cif file (string)

  • If source=’cid’, this should be a PubChem CID (string or int)

  • If source=’rscb’, this should be a RSCB PDB ID (string)

  • If source=’cod’, this should be a COD ID (string)

  • If source=’ase’, this should be an ase.Atoms object

• source ({'file', 'mol', 'cif', 'cid', 'rscb', 'ase'}, optional) – The type of the input mol (default: ‘file’).

• style ({'bs', 'cpk', 'cartoon'}, optional) –

  Visualization style (default: ‘bs’).

  • ’bs’ → ball-and-stick

  • ’cpk’ → CPK space-filling spheres

  • ’cartoon’ → draws a smooth tube or ribbon through the protein backbone

    (default for pdb structures)

• displayHbonds (plots hydrogen bonds (default: True))

• cpk_scale (float, optional) – Overall scaling factor for sphere size in CPK style (default: 0.5). Ignored when style=’bs’.

• supercell (tuple of int) – Repetition of the unit cell (na, nb, nc). Default is (1, 1, 1).

• w (int, optional) – Width of the viewer in pixels (default: 600).

• h (int, optional) – Height of the viewer in pixels (default: 400).

• detect_BondOrders (bool, optional) – If True (default) and input is XYZ, uses RDKit to perceive connectivity and bond orders (detects double/triple bonds). Requires the rdkit library. If False, fallback to standard 3Dmol distance-based single bonds.

• display_now (bool, optional) – If True (default), renders the molecule immediately. Set to False to prevent immediate display when you plan to call further visualization methods provided by the molView class

• viewer (bool, optional) – If True (default), initializes the py3Dmol engine and prepares the 3D model. If False, operates in ‘headless’ mode: only geometric data is processed for analysis (volume, CM, etc.), saving significant memory for high-throughput processing.

• zoom (None, optional) – scaling factor

G2_theo(t, k, G0, Ginf, binf)

concentrations(order, t, binf, k)

Calculate the time-dependent concentrations of reactant A and product B.

This method derives the initial concentration (a0) from the fitted final product concentration (binf) using the stoichiometric ratio alpha/beta. It then computes the concentration profiles based on the integrated rate laws for the specified kinetic order.

Parameters:

• order (int) – Kinetic order (0, 1, or 2).

• t (array-like) – Time vector for the calculation.

• binf (float) – Final concentration of product B at t=infinity.

• k (float) – Rate constant.

Returns:

(a, b) where ‘a’ is the concentration array of reactant A

and ‘b’ is the concentration array of product B.

Return type:

tuple

Notes

• Order 0: Linear decay/formation until reactant exhaustion.

• Order 1: Exponential decay/formation.

• Order 2: Hyperbolic progression based on the 1/[A] linear relationship.

fit(k_guess, G_0_guess, G_inf_guess, A_0_guess, order=1)

Fits the selected kinetic model (Order 0, 1, or 2) to the experimental data.

This method uses non-linear least squares (scipy.optimize.curve_fit) to simultaneously optimize the rate constant (k), the initial and final physical property values (G0, Ginf), and the final product concentration (binf). Physical constraints are applied via parameter bounds to ensure k and binf remain positive.

It includes automated ‘Smart Guessing’ for k, based on initial rates and computes information criteria (AIC/BIC) for model selection.

Parameters:

• k_guess (float) – Initial estimate for the rate constant (k).

• G_0_guess (float) – Initial estimate for the physical property at t=0.

• G_inf_guess (float) – Initial estimate for the physical property at t=infinity.

• b_inf_guess (float) – Initial estimate for the final product concentration [B].

• order (int, optional) – Kinetic order of the reaction (0, 1, or 2). Defaults to 1.

Returns:

A dictionary containing the optimized parameters (‘k’, ‘G0’, ‘Ginf’, ‘binf’)

and statistical metrics (‘RMSE’, ‘R2’, ‘t_half’). Returns None if optimization fails to converge.

Return type:

dict

Notes

• For Order 1, the timing is independent of binf, and alpha is coupled with k; hence binf is kept fixed during optimization.

• For Orders 0 and 2, binf and stoichiometry (alpha, beta) explicitly define the reaction’s capacity and end-point timing, ensuring physical consistency between the plateau and the slope.

get_best_order(verbose=True)

Determines and prints the best model based on the lowest RMSE.

halflife(order, binf, k)

Calculate the half-life (t1/2) for the reaction based on the kinetic order.

The half-life represents the time required for the reactant concentration to reach half of its initial value (a0/2).

Parameters:

• order (int) – Kinetic order (0, 1, or 2).

• k (float) – The optimized or guessed rate constant.

Returns:

The calculated half-life value.

Return type:

float

Notes

• Order 0: t1/2 = a0 / (2 * alpha * k) -> Dependent on a0.

• Order 1: t1/2 = ln(2) / (alpha * k) -> Independent of a0.

• Order 2: t1/2 = 1 / (alpha * k * a0) -> Inversely proportional to a0.

static load_from_excel(file_path, exp_number, sheet_name=0, show_data=True)
