As the first step in making assignements of the low-frequency vibrations of para-substituted benzene compunds, complete vibrational assignments of several representative compounds have been started. While assignements have been made for many monosubstituted benzenes, there is need for a complete assignment of a monosubstituted benzene with an electron-attracting subtituent. To fill this need, an assignment of benzonitrile has been made. Attempts to prepare benzonitrile-d5 were unsuccessfull, but are being continued. To confirm the previous assignments of phenol, a sample phenol-2, 4, 6-d3 was prepared. A complete vibrational assignment of this molecule has been made. Attepmts to prepare phenol-d5 are in progress. The assignements of p-cresol and deuterated p-cresols has been carried almost to completion. Using the vibrational assignements mentioned above as a foundation, the low-frequency vibrations of 28 para-substituted benzene compounds have been assigned as completely as possible. It has been shown that certain of the low frequency vibrations are sensitive to the nature of the substituent.
