| Abstract: | The structures of substitutedN-aminonitropyrazoles and 1- and 2-amino-4-nitro-1,2,3-triazoles as well as the site of protonation of 1-aminopyrazole were determined based on the1H,13C, and15N (14N) NMR spectra. The13C NMR spectra were recorded under conditions of13C-{1H,14N} triple resonance. Effects of substituents in the pyrazole ring on the13C and14N chemical shifts were studied. The13C,1H and15N,1H spin-spin coupling constants, obtained using techniques of [1H] 13C and [1H]15N polarization transfer (SPT, INEPT), were measured, fully assigned, and discussed.Translated fromIzvestiya Akademii Nauk.
