Paper Abstract

The theory of linked groupings of vibrational-rotational interactions in molecules has been applied for the construction of the infinite series for effective dipole moments of one quantum vibrational transitions. The necessary and sufficient symmetric selection rules for forbidden transitions dipole moments have been developed. All aspects of the removal of prohibition from fully symmetric fundamentals of nonpolar molecules have been investigated. Mechanisms of activation of other inactive fundamentals of nonpolar molecules are considered also. Ab initio calculation of dipole moment function and the evaluation of the effective transition dipole moments for CH4 molecule are presented.
