CCL:G: raman relative intensity

 Sent to CCL by: Cory Pye [cpye^^crux.smu.ca]
 Firstly, make sure that you are using the right experimental comparison. Raman
 spectra are usually reported in the "I" format, whereas it is the
 "R" format
 that can be related directly to the scattering activity. There is a frequency
 factor and a Bose-Einstein factor that you have to multiply by to interconvert
 them.
 Secondly, the intensity of the band is related to the area not the peak height.
 If a band is very broad, it might appear to be not that intense compared with a
 sharp peak, but the integrated band could be idenatical.
 Thirdly, sometimes theoretical predictions may swap two bands. No amount of
 uniform scaling will fix that. Also Fermi resonances can mess things up,
 sometimes.

 from Gaussian calculation by multiplying (n-n0)^4/n*C since the exponential term
 was giving value of 1.But with that the intensity at the lower wavelength was
 very low compared to the higher wave no. and the data did not match at all with
 the experimental data.Am I doing any mistake?
