Keyword EFIELD

With this keyword an external homogeneous electric field can be specified.
Options:

$<$Real$>$

Three real numbers that give the x, y and z components of the external electric field in atomic units.

Description:
The external electric field will be added to the core Hamilton operator by multiplying with the corresponding dipole moment matrices. The SCF is then converged with this modified core Hamilton operator. The electric field components must be given in atomic units by real numbers.
