W. Kozminski et al., N-15 AND C-13 SOLID-STATE NUCLEAR-MAGNETIC-RESONANCE STUDY OF 5-THIOMETHYLTETRAZOLE, Solid state nuclear magnetic resonance, 4(2), 1995, pp. 121-124
N-15 and C-13 cross-polarization magic-angle spinning nuclear magnetic
resonance (CP-MAS NMR) spectra of 5-thiomethyltetrazole have been mea
sured. Two kinds of tetrazole molecules are found in the hydrogen bond
chain system depending on the configuration of the S-CH3 group in rel
ation to the ring hydrogen atom. The two-dimensional N-15 CP-MAS exper
iment excludes the possibility of proton tautomeric dynamics in this s
ystem.
