✦ Synopsis
The angular correlation functions of the perpendicular infrared transitions of linear polyatomic molecules in the diluted gas phase and in dense media are represented as limiting cwx of the angular correlation functions of the perpendicular infrared rransitions of symmetric-top molecules with the Coriolis coupling constant r equal i-1.
Angular corr&lation functions (ACF's) are widely used for the description of the average rotational motion of moiecules in dense media. Experimentally
