Abstract

Infrared (4000-400 cm-1) and Raman spectra (4000-100 cm-1) of six trans-azobenzene isotopomers, including the parent one, were recorded. Using mono and double 15N-labelled isotopomers, the assignment of the N=N stretching was confirmed at 1439 cm-1 in the parent isotopomer. This vibration is strongly coupled with the phenyl mode 19b. In isotopomers with one and two perdeuterium-labelled phenyl groups the N=N stretching shifts to higher wavenumbers, since this coupling is no longer effective.
