  I am looking for code that will calculate
 the  symmetric and asymmetric vibrational stretching
 frequencies (the bending frequencies would be a bonus)
 of a simple (linear symmetric) triatomic system, given only the energies at
 a few geometries. I don't want to have to resort to
 doing this in cartesians because my energy calculations
 take too long, so running the 30 or so points that would
 be required is beyond my scope.
 	If any-one has anything suitable,that they are prepared
 to let me use, or knows of  where i can find such a beast, i would be
 very gratefull.
