H , =C, ' \* N and 19%g N M R data were obtained for organomercury fuIminates, RHgCNO (R=Me, Ph, CNO). The relatively slow relaxation processes effective for the quadrupolar nitrogen muclei of these compounds allow the detection of -g-l4N scalar coupling constants. This feature is ascribed to the pr
