## Abstract The isotope effect induced by deuterium substituted species is observed in molecular properties, such as geometry, kinetics, and electronic state, of the molecules through nuclearβelectron interaction. Theoretical considerations and experimental alignments have been studied by ab initio

## Abstract The ^1^H chemical shifts of 124 compounds containing a variety of functional groups have been recorded in CDCl~3~ and DMSOβ__d__~6~ (henceforth DMSO) solvents. The ^1^H solvent shift ΞΞ΄ = Ξ΄(DMSO) β Ξ΄(CDCl~3~) varies from β0.3 to +4.6 ppm. This solvent shift can be accurately predicted (
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
