Re: CCL:NH3 Inversion Doubling

[Robert_Topper <topper \\at// magnum.cooper.edu>]

 On this topic I can provide no concrete advice other than to have a
 look at the following paper:
 "reaction path power series analysis of NH3 inversion," by R. Steckler
 and D.G. Truhlar, J. Chem. Phys. 93, 6570 (1990).
 In this paper it is noted that the inversion barrier height is quite
 sensitive to the number of basis functions used. This may be a useful starting
 point towards answering your question.
