Carbon‐13 nuclear magnetic resonance spectra of substituted‐s‐triazolyl tetrazoles

Abstract
The natural abundance carbon‐13 nuclear magnetic resonance spectra of various 5‐aryltetrazoles, 1‐(5‐aryltetrazol‐2‐ylacetyl)‐4‐phenyl thiosemicarbazides and 5‐(5‐aryltetrazol‐2‐ylmethyl)‐4‐phenyl‐s‐triazole‐3‐thiols were recorded using Fourier transform techniques. The chemical shifts of various carbon resonances have been assigned on the basis of chemical shift theory, the signal multiplicity observed in the single‐frequency off‐resonance decoupled (SFORD) spectra and comparison with the chemical shifts of the model compounds.
