## Abstract The OH chemical shift of the enol form of nitromalonamide is found at 18.9 ppm both in DMSOβ__d__~6~ and in DMFβ__d__~7~ indicating a very strong hydrogen bond. The OH chemical shift is insensitive to temperature changes. Contrary to the large OH chemical shift, a small twoβbond deuteri
The deuterium isotope effects on the "Si chemical shifts in several organosilanes and siloxanes have been determined. For silanes, the one-bond effects are approximately -0.2ppm per deuterium and follow an additivity relationship. The two-bond effect is small.
Large deuterium isotope effects on "0 resonances were observed for six common NMR solvents. Only in the case of acetone did the substitution of deuterium for hydrogen result in a downfield shift. The H/D isotope effect was also detected in a study of the reversible hydration of CH,CHO.
