Vibrational Spectra of Linear Molecule: Carbonyl Sulphide

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.
