✦ Synopsis
The stretching vibration-rotation Hamiltonian of tetrahedral molecules is derived in the local-mode model. The result shows that the effective rotational Hamiltonian of a local-mode state gives rise to symmetric-top rotational energy levels, which are quantitatively in good agreement with experiments.

A treatment of vibrational relaxation of impurity molecules in host solids is given, which introduces two improvements over existing theories: (i) The librational degree of freedom is taken into consideration. (ii) Local translational modes at the impurity site are included in the treatment. A reali

The present paper reports the derivation of a new theoretical model describing the rotation and vibration of a triatomic molecule. The new method is based on the MORBID (Morse Oscillatory Rigid Bender Internal Dynamics) method (P. Jensen, J. Mol. Spectross: 128, 478-501 (1988): P. Jensen. J. (hcm. S
