Abstract:

Frequency assignments in the CsBr spectral region 1650 to 1250 cm were made from the spectra of 279 benzene derivatives. The Raman spectra of 119 of these compounds were also available and were used as aids in making the assignments. The assigned frequencies include several benzenelike ring deformations and some vibrations that are either internal vibrations of the substituent group or involve the ring-substituent bond. A variation in frequency with symmetry or substitution type ortho, meta, para, etc. was found for the ring deformations. Within a given substitution type certain of the ring-deformation vibrations were found to be sensitive to substituent effects. The assigned frequencies involving the substituent group can be classified as characteristic frequencies of benzene compounds with a particular substituent. Author
