Sažetak
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 (N=N stretching and N-H/N-H-2 in-plane bending) of the protonated and deuterated species is proposed. The N=N stretching band in irans-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.
