Abstract [en]

Averbukh (1990) found that the only interpretations of parameters in the Mayants-Averbukh IR and Raman intensity theories, in terms of electro-optical parameters, which are in conformity with the rotational mode equations are those of the respective valence-optical intensity theories in zeroth-order approximation. Averbukh used the same approach as had been used by Rupprecht (1981, 1984) but did not split the resulting tensors into irreducibel parts, which facilitated his work. To further confirm Averbukh's results, an alternative and more united and direct approach is used in the present work. The conditions of the generalized valence-optical IR and Raman intensity theories in zeroth-order approximation are applied on both sides of the rotational mode equations of the corresponding Mayants-Averbukh intensity theory. This gives directly correct results without invoking symmetry arguments. The present approach has also revealed an intrinsic beauty hidden in the formalism.
