Research Abstract |
A technique of molecular orientation analysis in thin films having a coarse surface using Raman spectroscopy has been developed, so that the results would be discussed with those obtained by MAIR spectroscopy. Visible LASER light can be sharply focused on a sample, which is impervious to the surface roughness of the sample. In addition, the C=C and N≡N stretching vibration bands that are not observed by IR spectroscopy can readily be analyzed by Raman spectroscopy, which is a great benefit to reveal isomeric and anisotropic structures. In the present study, to analyze anisotropic structure quantitatively, highly accurate polarization Raman spectrometer has been built, which corresponds to measurements using the Z-polarization. An exact theory considering anisotropic LASER irradiation and light scattering processes has also been developed for drawing quantitative molecular information from the polarized Raman spectra.
