The hydrogen sulphide molecule(H2S) is one of the best experimentally studied aymmetric top molecules that shows a pronounced localisation of molecular vibrations.Both the discrete variable representation for three-dimension(DVR3D) program and modified DVR3D program have been used to determine the vibrational energy levels of the fundamental electronic state of H2S and its isotopmers(HDS,D2S).
