It appears that we have a cyclical offset in assigning vibrational mode vectors to energies in the GAMESS reader 11.9.35_dev . Highest energy is showing up with the motions of one of the rotations and one rotation is showing up with low energy bending. I think this is a file reader error and not the data file, but I haven\'t got time to check now. Logging this in so that I don\'t forget.

Definitely and 11.9 problem. Works OK in 11.8
fixed for 11.9.36.
