Coordinate applied to perform Raman susceptibility cal ?

Post by orpong » Wed Apr 28, 2010 6:37 am

Dear All,

Which coordinate applied to perform Raman susceptibility calculation?

These are my support information.

(1) From dataset#5 of tnlo2 tutorial (as shown below) and description of rfdir parameters, can I summerize that: genneraly, Raman susceptibility performed in coordinate of primitive vectors.

(2) In cubic AB crystal (for example, PHYSICAL REVIEW B 71, 125107), these primitive vectors had been written in term of cartesian coordinate ?
