A quantitative assessment of the content of the 1,5-tautomers is made from the overall contribution to the total ion current from the individual fragment ions responsible for a specific tautomeric form in the series of 1-aryl-3-phenyl-5-(2-benzothiazolyl)formazans.It was established that the tautomer in which the mobile proton is localized at the nitrogen attached to the benzothiazole residue predominates in the gas phase.A correlation analysis was undertaken with regard to the contributions from the tautomers to the composition of the molecular ion.It is suggested that the stereochemical structure of the formazans in the crystalline state (x-ray phase analysis) corresponds to the structure of the molecular ion.
