Dear Tian,

Many thanks for the reply. I will try with the Gaussian!

Hello,

Pre-resonance raman is very different to common Raman spectrum (off-resonance Raman). Currently Multiwfn doesn't explicitly support simulating pre-resonance Raman spectrum based on ORCA output file.

Best,

Tian

For the mistake about previous question, I editted the question.

Hi, Tian. First, thank you for sharing this great software.

I am now trying to simulate pre-resonance raman spectrum from the Orca.

I made input following 3.13.2 in manual using numfreq keyword. And I get a .out file from the calculation results.

But, when I open .out file through Multiwfn, there are no options for setting wavelength of incident beam.

Qustion. How to set the any incident light wavelength by myself to perform pre-resonance Raman simulations in Multiwfn?

Here, I copied my input file for the calculation of orca.
The Cartesian Coordinate of this file came from Opt Freq calculation. I want to set incident beam wavelength as 460 nm.
