Isotope effects in the nmr spectra of nitromethane

Abstract The high-resolution 1 H, 13 C, 14 N, 15 N, and 17 O NMR spectra of some isotopomeric nitromethanes have been obtained and all possible coupling constants have been measured. The one-bond 17 O 15 N coupling constant has been found for the first time. The program QUADR has been applied to analyze the 13 C 14 N multiplets in the 13 C NMR lineshapes modified by the 14 N quadrupole effects. 2 D 1 H isotope effects on some coupling constants and 2 D 1 H , 13 C 12 C , and 15 N 14 N isotope shifts for 1 H, 13 C, and 15 N nuclei have been also established.
