EXCITATION PROFILES OF RESONANCE RAMAN SCATTERING AND FLUORESCENCE IN DYE MOLECULESS. Kinoshita, J. Watanabe et T. Kushida

The excitation spectra for the Raman and luminescence components of β-carotene have been measured in solutions over a wide spectral range using ion lasers and tunable dye lasers for excitation. The intensity ratio of the fluorescence to Raman scattering has been found to decrease rapidly when the exciting wavelength is tuned away from resonance. This result clearly shows the importance of the non-motional narrowing effect. The experimental data are compared with existing theories that take into account the non-motional narrowing effect.
