Electron Scattering and Internal Rotation

摘要

Theoretical functions are developed which facilitate the analysis of electronhyphen;scattering data from molecules which undergo internal rotation. The probability distributions for distances whose equilibrium positions occur anywhere on the circle of rotation are derived taking into account the combined effect of the overhyphen;all vibration of the molecular frame and the torsional motion. The extremes of small oscillations and free rotation are treated in detail.
