“…The static deuterium quadrupolar coupling constant G4q) (where AQ = e2qQ/h) is 170 kHz for aliphatic C-2H bonds (Burnett & Muller, 1971) and 175 kHz for olefinic C-2H bonds (Kowalewski et al, 1976). In eq 1, the notations introduced by Petersen & Chan (1977a,b) have been used with Sc^h = SJSf (with = y).…”
