A normal co-ordinate treatment has been carried out to calculate the force constants of BH3CO and BD3CO molecules, on the basis of a Urey-Bradley potential force field.
Volume 57 Issue 3 March 1963 pp 181-185
The force constants of SF4 molecule have been evaluated using the Urey-Bradley force field and compared with those obtained by F-G matrix method. Using the Urey-Bradley constants, the fundamental vibrational frequencies are calculated and compared with the observed frequencies.

The theory of the determination of the mean amplitudes of vibration in molecules using the symmetry co-ordinates has been applied to the cases of arsenic halides belonging to the pyramidal XY3 type and a few silicon and stannic halides of the tetrahedral XY4 type. The mean square amplitudes and mean amplitudes of vibration have been evaluated at 298° K.
