rdkit.Chem.Graphs module¶
Python functions for manipulating molecular graphs
In theory much of the functionality in here should be migrating into the C/C++ codebase.
- rdkit.Chem.Graphs.CharacteristicPolynomial(mol, mat=None)¶
calculates the characteristic polynomial for a molecular graph
if mat is not passed in, the molecule’s Weighted Adjacency Matrix will be used.
The approach used is the Le Verrier-Faddeev-Frame method described in _Chemical Graph Theory, 2nd Edition_ by Nenad Trinajstic (CRC Press, 1992), pg 76.
