FCBand FCBand is a Python package for simulating vibronic bands of electronic absorption spectroscopy using the Franck-Condon displaced harmonic oscillator (FC-DHO) models. These models are suitable for simulating the unresolved vibronic band shapes of electronic spectra that involve many electronic transitions and vibrational modes. https://comp.chem.umn....

ErtlFunctionalGroupsFinder A Java library for automated functional group implemented with the Chemical Development Kit (CDK) program. It should run on Windows/Mac/Linux operating systems. It relies on the Ertl algorithm, which is also used by the RDKit for functional group detection. A key difference between the two implementations seems to be in their ...

LEVEL For a diatomic molecule, LEVEL can calculate all Franck-Condon factors (FKF): $$|\langle \psi_{v,J} | \psi_{v^\prime,J^\prime}\rangle|^2\tag{1},$$ between rovibrational levels $(v,J)$ of one potential energy curve, and $(v^\prime,J^\prime)$ of another potential energy curve (or the same potential energy curve). To calculate FKF, the variable LXPCT ...
