Raman Spectroscopy: Why Peaks of Stokes Higher than Anti-Stokes?

[fricke]

Why do peaks of Stokes higher than peaks of anti-Stokes in graph of absorbance unit against wave number?

Because anti-Stokes typically takes place when the initial state is an excited state.

Thank you for your reply!
So, anti-Stokes has lower peaks than Stokes because its initial state is an excited state where the population of electrons at excited state is lower than the ground state? Does it make sense?

Basically yes.
