Abstract
IN a recent letter, Heath and Linnett1 suggested for the treatment of molecular vibrations a new force field, the orbital valency force field. This is based more closely on modern ideas of directed valency than is the simple valency force field. We decided to test the orbital valency force field on methane, which is a convenient molecule to use, since all the deuterium-substituted methanes have been studied2. The first result obtained was that the original theory failed in this case. In particular, for CH4 and CD4, it was found that, to explain the frequencies of the doubly degenerate bending vibrations, a bending constant (kH/r2) of 1·35 × 105 dynes/cm, was required, whereas the triply degenerate bending vibrations needed a constant of 0·86 × 105 dynes/cm. Bending motions which are members of these two degenerate sets are shown in the accompanying drawings.
