WebThe short answer is that Gaussian uses a coordinate system where the normalized cartesian displacement is one unit. This differs from the coordinate system used in most texts, where a unit step of one is used for the change in interatomic distance (in a diatomic). The vibrational analysis of polyatomics in Gaussian is not different from that ... WebNIST Technical Series Publications
