Abstract
Near-infrared Fourier transform (NIR FT) Raman spectra of five trans-azobenzene isotopomers and their protonated and deuterated forms were recorded. Trifluoroacetic acid was found to be a good protonation agent for measuring Raman spectra of protonated azobenzene. An assignment of the most relevant vibrational modes (NN stretching and N H N 2 H in-plane bending) of the protonated and deuterated species is proposed. The NN stretching band in trans-azobenzene isotopomers decreases by about 40 cm −1 upon protonation, while it varies within ± 10 cm −1 upon deuteration with respect to the unprotonated (undeuterated) form. A comparison is made with the protonated form of the isoelectronic trans- N-benzylideneaniline.
