Example: Polarizabilities including spin-orbit coupling: AgI¶

#! /bin/sh


# Example shows an frequency-dependent ZORA calculation of complex linear
# response of AgI including spin-orbit coupling.

# The polarizability is calculated using the AORESPONSE key, in which spin-orbit
# coupling is taken into account. In this case a spin-restricted calculation is
# required, but, unlike the rest of AORESPONSE, also NOSYM. In this example
# lifetime effects are included.
