Abstract
The stretching and bending vibrations of methane are studied in a local anh armonic model of molecular vibrations. The use of symmetry-adapted operator s reduces the eigenvalue problem to block diagonal form. For the 44 observe d energies we obtain a fit with a standard deviation of 0.81 cm(-1) (and a r.m.s, deviation of 1.16 cm(-1)).
