### Two-photon transition tensor derivatives

Posted:

**27 Jun 2019, 12:22**Dear Dalton Community,

I want to get first derivatives of two-photon transition tensor with respect to normal coordinates. Can Dalton do it automatically? If not, maybe it is possible to run **RESPONSE module at every geometry generated via *WALK .NUMERI?

Best regards,

Olya
