Hello everyone.

I would like to compute the dynamic hyperpolarizability value of a molecule using Gaussian on Linux OS. I have read that the essential keywords to include for such request are the #polar and CPHF=RdFreq. However, where exactly do I specify the frequency in the input stream?

Here is my route section (I'm welcoming any comments if there's a mistake in this command).

#p polar cphf=rdfreq b3lyp/6-31g(d) geom=connectivity
