Description of Molecular Distortions III. Trigonally-Planar XY3 Molecules

Abstract

Second-rank tensors were used to calculate the degree of distortion for the NO3 ions in a number of crystalline compounds. All NO3 ions appear to be strictly planar, as found in a previous study1. A significant correlation, between the main components of the tensor and the wavenumbers of the components of the antisymmetric stretching vibration (r3) of the NO3 ion, was found
