TAMkin is a post-processing toolkit for normal mode analysis, thermochemistry and reaction kinetics. It uses a Hessian computation from a standard computational chemistry program as its input. CHARMM, CP2K, CPMD, GAMESS, GAUSSIAN, QCHEM and VASP are supported. Multiple methods are implemented to perform a normal mode analysis (NMA). The frequencies from the NMA can be used to construct a molecular partition function to derive thermodynamic and kinetic parameters.
