β¦ Synopsis
Infrared absolute band intensities of the nonplanar vibrations were measured for p-terphenyl in CS, solution in order to determine the molecular structure in the solution state. The normal coordinate treatments were carried out for the seven representative conformations of p-terphenyl due to the torsions about the two C-C bonds between phenyl rings. Considering the vibrational modes obtained, the nonplanar band intensities were calculated for both of the fundamentals and their combinations of the seven conformations. Comparison between the calculated and the observed intensities resulted in almost unequivocal assignments of the nonplanar bands and also led to some informative results for understanding the conformation in the solution state.
