Raman Spectra: Stokes vs Anti-Stokes - Get Answers Here!

[Botttom]

Hello,

In most of the papers like

http://eprints.qut.edu.au/4763/1/4763.pdf

one sees the raman spectra of crystals or molecules and the peaks are not further described (if they are stokes or antistokes). Do all the Peaks belong to the Anti-stokes-lines? And if it is so, why don't we see any stokes-lines?

Thanks

Raman processes are rather rare events (compared to the Rayleigh peak), with, in general, Stokes scattering occurring more often than Anti-Stokes events. This leads to instrumentation that uses the Stokes "regime" to collect data.

Not really a source, but nevertheless some resource: http://www.raman.de/htmlEN/basics/intensityEng.html

Ok thank you
