Infrared spectra in polarized light of crystalline chloroform

Mostrar todas las versiones(3)

High resolution spectra in polarized light of oriented crystalline films of chloroform at 77°K were obtained. The ratio of intensities of Davydov components for different angles of polarization were also determined. Comparison with the oriented gas model approximation allowed the assignment of compo...
