 Hi, I am using Gaussian 03 to find some coupling constants; however, I am using
 very large structures, and I just need the coupling constants of 3 specific
 atoms, so, I would like to know if any of you know the keyword, and where and
 how to put it in Gaussian, in order to calculate just the coupling constant of
 the atoms I need and do the calculation much faster. I know is possible, I just
 do not know how.
 Thanks a lot
