# Relation between RAMAN Intensity and Energy of the photon

Hi all,

What is the relation between RAMAN Intensity and Energy of the photon and/or bond stregth and/or bond energy? Is there any equation or sth explain it easily? If you can explain it in a simple way, I will appreciate.

Thanks

Hi,
It is difficult to say directly. In general Force constant/stiffness (FC) is proportional to height/intensity of peak and also its position.
FC is inversely proportional to bond length (more length then less stiffness!). Also root mean square displacement (rmsd) will be more for the highest peak.
This is what came to my mind when I read your question.
Cheers, Rajini.
