Quadrupole Coupling of the Deuteron in DCCCl and DCN

摘要

The quadrupole coupling of the deuteron (eqQ)Dwas measured in DCCCl where it was found to be +175plusmn;20 kc/sec. A less accurate determination of the absolute value (eqQ)Din DCN yielded approximately 290 kc/sec. The field gradient,q,at the deuterium nucleus in DCCCl is +8.85plusmn;10 percenttimes;1014esu. A calculation ofqbased on a Hundhyphen;Mulliken molecular model yields aqof the same sign as that observed but approximately twice as large, indicating the insufficiency of the model for such detailed calculations.
