摘要：

N-15-N-15 and N-15-C-13 spin-spin couplings are reported for seven N-15 labeled 1-oxa and 1-thia-2,3,4-triazoles and three sydnonimines. For the former class of compounds the spin-spin coupling data show a close similarity between the N2-N3 and N3-N4 bonds which had not previously been suspected from chemical shift measurements.
