Dear Loc Duong Dinh:
First of all, there are four modes which are below zero:-49, -1,-0.9, -0.15
Are you sure it is right?

The raman intensities is realy dependent on geometry configuration.
The cross section is base on PRB 54, 7830 (1996) and refs quoted therein.

Searching in the maillist, you can get more information.
