Vibrational Spectra of Linear Molecule: Carbonyl Sulphide

Abstract

In this chapter, vibrational spectra of Carbonyl sulphide (OCS) in fundamental level and at higher overtones calculated by Lie algebraic method. In this method Hamiltonian expressed in terms of invariant and Majorana operators, describe stretching vibrational frequencies. The Hamiltonian is an algebraic one and so far all the operations in this one dimensional Lie algebraic method, unlike the more well-known differential operators of wave mechanics.
