Now, I am interested in molecular geometry under applied electric filed. Then,
I want to use $EFILED option. In this option, the electric field is given as
EVEC array. I have questions.
Q1: What is the unit of the electric filed? V/m ?
Q2: How to express EVEC array? I guess EVEC(1)=Ex, Ey, Ez ,where Ex, Ey
and Ez are actually numerical values. Is this OK?
Thank you in advance.
