title: A study of the possible and preferred site of protonation in 7-methyl-1,5,7-triazabicyclo[4,4,0]dec-5-ene by vibrational spectroscopic methods.
abstract: The normal co-ordinate analysis have been carried out for 7-methyl-1,5,7-triazabicyclo[4,4,0]dec-5-ene (MTBD) and its three possible protonated tautomeric forms. The calculations and measured infrared (IR) spectra are consistent with a tautomeric species in which the proton is attached to an imine nitrogen atom.
