摘要:

AbstractCarbon–proton and carbon–deuteron coupling constants were measured in the isotopomers CH2Cl2, CHDCl2and CD2Cl2. The primary and secondary isotope effects on the carbon–proton coupling are −0.60 (±0.05) and −0.25 (±0.01) Hz, respectively. The deuterium‐induced13C isotope shifts proved to be almost linearly dependent on the number of deuterium atoms, although there is a small but significant n
