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

Download HF_ResonanceRaman.run

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 ADF input one then needs to include the subkey FREQUENCIES of the key GEOMETRY (numerical frequencies) and include the subkeys RAMAN and LIFETIME of the key AORESPONSE.
