Abstract:
15N and 13C cross-polarization magic-angle spinning nuclear magnetic resonance (CP-MAS NMR) spectra of 5-thiomethyltetrazole have been measured. Two kinds of tetrazole molecules are found in the hydrogen bond chain system depending on the configuration of the S-CH3 group in relation to the ring hydrogen atom. The two-dimensional 15N CP-MAS experiment excludes the possibility of proton tautomeric dynamics in this system.
