Abstract
In this paper, we have calculated vibrational frequencies of Carbonyl sulphide (OCS) in fundamental level and at higher overtones by Hamiltonian expression, which is in terms of invariant and Majorana operators, describe stretching vibrations. The Hamiltonian is an algebraic one and so far all the operations in this method, unlike the more well-known differential operators of wave mechanics.
Keywords: Vibrational spectra, carbonyl sulphide, U(2) Lie algebraic method.
