The main problem comes from the "standard orientation" of th= e coordinates. Since MOLPRO, MOLCAS, and GAMESS use different standard orie= ntations for a given symmetry, one has to read their source codes to unders= tand these=A0standard orientations. If the relationship between two differe= nt=A0orientations is known, one may construct a rotation matrix to rotate t= he Cartesian coordinates and the orbitals.=A0A simpler way is to not use sy= mmetry, which will reduce the usefulness of the program.

In addition, the transformation method between Cartesia= n and spherical functions is not unique. The convention in that paper is fo= llowed by Gaussian, NBO, MOLPRO, GAMESS, and so on, but not by MOLCAS and s= ome other programs. This means that only Cartesian basis functions can be u= sed in your GAMESS and MOLCAS calculations. However, this may lead to some = numerical instabilities in some calculations (for example, relativistic DKH= ).

I hope this will help.

Hi All,

I would like to see if someone, somewhere has a script or program that can = convert ROHF orbitals from a Molcas Rasmol file into something readable wit= h Gamess-US. =A0I am aware this is not a trivial scripting exercise since M= olcas uses pure spherical harmonics while Gamess reads and outputs orbitals= in Cartesian format (even when running calculations using real spherical h= armonics).

Might someone know of a portable program that does the necessary transforma= tions as Frisch and Schlegel outline?

I checked the archive and see this issue was brought up a few years ago, bu= t I couldn't find a solution posted.

Thanks for your time,
