摘要

Abstract 15 N NMR shielding measurements reveal that thiolo-imidazole and-tetrazole exist almost entirely as the thione form. Quantitative estimates of the position of tautomerism in 1, 2, 3-triazole and tetrazole are obtained. The reported assignments are supported by means of INDO/S-SOS shielding calculations.
