[molpro-user] Calculating Transition Dipole Moments

[Kirk Peterson]

Dear Samir,

hard to tell without an input file, but it looks like perhaps you are specifying the dipole moment operator by “trdmz” rather than by just dm. See section 6.13 of the manual (http://www.molpro.net/info/current/doc/manual/node68.html#sec:gexpec <http://www.molpro.net/info/current/doc/manual/node68.html#sec:gexpec>).  TRDMZ is just the variable that contains the value of the z-component of the transition dipole moment after it is calculated.

regards,

-Kirk
