Stimulated Raman scattering activity of organic compounds
Vibrational Spectroscopy , Volume 5 - Issue 3 p. 337- 344
The stimulated Raman scattering (SRS) activity of over one hundred organic compounds was investigated at room temperature. Spectra were obtained successfully for the colourless neat liquids but not for the solid chemicals in solution, and their SRS shifts were measured systematically. The results confirmed that SRS Stokes shifts are usually the same as those observed in spontaneous Raman scattering, with occasional differences in frequency from the strongest spontaneous Raman bands. Empirical trends have been observed in functional group recognition, compound classification, degenerate vibrational modes, substituent group effects, hydrogen bonding and concentration threshold. Other new observations such as multiple peaks, exceptional SRS activity and distributed spectra are also reported. SRS offers several advantages over normal Raman spectroscopy in industrial process monitoring, and a potentially interesting scope of analytical utility is discussed.
