AN INTERPRETATION OF INFRARED INTENSITIES OF POLYATOMIC MOLECULES

Address of Person: Department of Chemistry, University of Florida, Gainesville, FL 32611.Author Institution:An analysis of infrared intensities of fundamental vibrations can be made to obtain the contributions from the notions of $\underline{each atom}$ to the intensities as a corresponding PED (potential energy distribution) analysis of the normal modes of vibration. If nothing else, it certainly provides a basis for the critical examination of calculated intensity parameters (atomic polar tensors, APT), and it offers some physical insight into the understanding of vibrational intensities of polyatomic molecule
