# Example for a singlet excited state geometry optimization for N_2.

# Needed for such excited state optimizations are the key EXCITATIONS (to
# calculate excitation energies), the key GEOMETRY (to do a geometry
# optimization) and the key EXCITEDGO (to select for which excitation a geometry
# optimization should be performed). In this case a hybrid functional B3LYP is
# used.
