Analytical expressions for matrix elements of the dipole moment operator for internal rotation are obtained. Quantitative measures for spectroscopic parameters of transitions associated with specific potential wells on the potential energy surface (conformers) are proposed. The relations obtained are illustrated by numerical examples and diagrams.
