Abstract

Infrared absolute band intensities of the nonplanar vibrations were measured for biphenyl in CS2 solution, and the data made it possible to determine the dihedral angle between the two phenyl rings of biphenyl. The potential barrier for the internal rotation around the central C-C bond was also determined from the deuterium spin-lattice relaxation times for fully deuterated biphenyl in Me2SO solution by using Woessner's theory. These two results enabled us to obtain the potential function for the internal rotation of biphenyl in solution. The potential function thus obtained was found to be quite close to those calculated theoretically.
