Proton NMR spectra are reported for chlorotrimethylstannane, tetramethylstannane, tetramethylplumbane and dimethylmercury containing various combinations of CH, and CD, groups. Additive long-range isotope effects on chemical shifts, 4AH(D), are observed to result in increased shielding of essentiall
