Hello,
When a numerical Hessian calculation is done, we can easily get the derivative of the dipole moment with respect to 3N cartesian displacements.
However, this property is not printed in an analytical Hessian calculation. I wonder if this property is computed during an analytical Hessian calculation (but simply not printed), or it is just not computed?
The transition dipole moments are printed with respect to the vibrational modes after a Hessian calculation, so I imagine, it should also be possible to get it with respect to the cartesian coordinates as well?
long story short, can I somehow get the derivative of the dipole moment with respect to cartesian displacements analytically in Q-Chem? (ideally during a Hessian calculation)
Thanks!
Selim
