Origins of conformational equilibrium isotope effects for hydrogen in ketones
Carr CA., Robinson MJT., Webster A.
Conformational equilibrium isotope effects for hydrogen in cyclohexanones and other ketones are consistent with (i) hyperconjugation, (ii) analogues of hyperconjugation, and (iii) a difference in polarity between C-H and C-D bonds; steric effects are relatively unimportant. © 1989.
