On 'cross' spectral moments of the collisional polarizabilities of rigid rotors

The 'cross' spectral moments due to collision induced phenomena are considered. We show that for linear rigid rotors it is possible to obtain analytical formulae for these 'cross' terms. The general expressions are valid for arbitrary orders of moments and for arbitrary tensorial...

Zusammenfassung:	The 'cross' spectral moments due to collision induced phenomena are considered. We show that for linear rigid rotors it is possible to obtain analytical formulae for these 'cross' terms. The general expressions are valid for arbitrary orders of moments and for arbitrary tensorial multipolar intermolecular interactions. Statistical averaging is performed, using the spherical components g l 1 l 2 α (R 12 ) of the pair distribution function. It makes the formulae suitable for numerical computations.
