The goal of this work is to illustrate how we can Validate the results
of quantum-mechanical calculations at different levels of theory by c
areful analysis of the INS spectra. We have carried out this procedure
for different azines: 1.3.5-triazine (s-triazine), trichloro-s-triazi
ne and 1,4-diazine (pyrazine) with satisfactory results. (C) 1998 Else
