Example: Resonance Raman, excited state finite lifetime: HF¶

#! /bin/sh

# Example shows a calculation of the Resonance Raman spectrum (RRS) of HF. In
# this example the RRS is calculated from the geometrical derivatives of the
# frequency-dependent polarizability, including a finite lifetime.

# In the AMS input one then needs to request 'Raman' in the 'Properties' block 
# and specify 'IncidentFrequency' and 'LifeTime' in the Raman Block

# Note that used basis set is too small to get accurate results.
