Abstract
Using Lie algebraic method, we report a study of the vibrational frequencies of various metallotetraphenyl porphyrins and its cation radicals, i.e. Cu[TPP], Cu[TPP]+, Ni(TPP), Ni(TPP)+, ClFe(TPP) and ClFe(TPP)+ for 60 vibrational bands each using U(2) algebraic model Hamiltonian. Intermode couplings in algebraic models have been included to achieve improved RMS deviations as well as to get deep insight into detailed spectroscopy for these tetraphenyl porphyrin molecules.
