内容記述タイプ Abstract
内容記述 The infrared spectra of thin urea and thiourea films, several hundred Angstroms thick, on a steel plate were obtained using an optical system in which the beam polarized parallel to the plane of incidence was incident at 70° upon a steel plate covered with film. The spectra obtained showed that the c-axis of the urea crystal was parallel to the metal surface. However, the abnormal behavior of the NH_2 bending and the NH_2 twisting bands suggests that the urea molecule in the film was deformed from the planar structure. The intensities of the infrared bands of thiourea belonging to the B_1 species decreased in the film, and it may be concluded that the c-axis of the crystal is nearly parallel to the metal surface. The considerable rise in frequency of the NH_2 wagging band observed in the thin thiourea film may arise from the deformation of the crystal. As for the thiourea-collodion film, thiourea A_1 bands appeared to be very weak, corresponding to the C=S bond orientation parallel to the metal surface. The dichroism of the thiourea bands in the 3μ region obtained about the thiourea and thiourea-collodion thin films is in agreement with the Badger-Waldron assignment of the absorption bands.
