- 中文摘要:
Raman spectrum of powdered crystalline trans-stilbene is recorded by a laser Raman spectrometer. The intensity of a low frequency skeleton bending vibration at 220 cm¯1is observed to be very weak. Its Raman intensity, after corrected for the photocathode response and for the v4 scattering factor, agrees within 10% of the theoretically calculated value. It is therefore proved that the intensity of a Raman active Vibration is proportional to the square of its vibrational frequency, if only one excited state is involved in the scattering process.
Lattice vibrations in trans-stilbene crystal are also reported. - 英文摘要: --
