Because aoforce does not support point groups having reducible E representations, we are performing NumForce calculations on such molecules. However, the last step in a NumForce calculation is the aoforce frequency analysis of the hessian generated by sammler. The results given by aoforce seem to be reasonable, so I suppose that the problems with aoforce and reducible E representations only affect actual analytic 2nd derivative calculations and not the frequency analysis part? I just wanted to check this, as the aoforce.out file contains the usual warning "It is STRONGLY RECOMMENDED to use a lower symmetry!"
