摘要：

Resonance Raman spectra of 1-, 3-, and 9-monolayer Langmuir-Blodgett (LB) films of 2-(4'-dioctadecylaminophenylazo)-N-methyl-benzothiazolium perchlorate (Azo II) have been measured with high signal-to-noise ratio and compared with those of the dye in the cast film and solutions. A band assignable to the N = N stretching mode is observed at 1458 and 1465 cm-1, respectively, in the LB film spectra and in the cast film and solution spectra. These observations suggest that Azo II takes a trans conformation around the -N = N- bond in the LB films as well as in the cast film and solutions but the conformation is slightly different between the LB films and the rest.
