The Normal Coordinates ofNhyphen;Dimethylaminodiborane

摘要

The multiple origin method has been utilized for the selection of initial coordinates for the description of the normal vibrations ofNhyphen;dimethylaminodiborane. Symmetry considerations were then used in order to obtain symmetry coordinates from these MOM coordinates, and, under the assumption of a diagonal potential function, these coordinates were assigned to vibrational frequencies which have been recently reported by Mann. The valence force constants for the methylhyphen;Nhyphen;methyl framework vibrations were then calculated and the results compared with similar constants obtained from the dimethylamine molecule.
