%X The selectivity of tritium labelling of double bonds by partial hydrogenation of the acetylenic analogue on Lindlar catalyst is investigated by 3H and 13C n.m.r. Examples of both the secondary isotope effect on chemical shift and the usefulness of 3H n.m.r, measurements to calculate proton-proton coupling constants are described. In the absence of proton coupling a finite difference (0.014 ppm) in the chemical shift of tritons at positions 9 and 10 of methyl (Z)-[9,10-3H]octadec-9-enoate is observed.
