As said, I can't find anywhere how to syntax an input with magnetic field applied. Does anybody know how to do it? I work with gaussian 03w but I guess the syntax for it hasn't changed.
Thank you for your reply Mr Nikitin! I actually want to study the magnetic properties of an atom or a compound that rises from the electronic magnetic dipole moment. In order to do this, I want to specify the orientation and magnitude of the magnetic field myself. Much like the case of the electric field, which you can determine with the keywords Field=X+10 etc. or with field = read. Is there anything analogous for the magnetic field?
It is not possible to apply magnetic field in Gaussian.
The London code developed by Helgaker et al. supports this, see http://londonprogram.org. Unfortunately, currently this code is not publicly available. Another choice is Chronus program (http://www.chronusquantum.org), you can have a try.
As previously said, there is no way to apply a magnetic field in Gaussian. I suggest to use the Dirac (Free) Code in the following link. http://www.diracprogram.org/doku.php
