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.

β¦ Synopsis
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.

## 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
17O chemical shifts were measured in 40 enamines activated in the b-position by CxO, COO, NO 2 , SO and groups. Data for the oxygen-containing series of o-hydroxyacyl aromatics are also included for com-SO 2 parison. Intramolecular hydrogen bonding in the enamines is discussed in terms of the accept
Over 100 isotope effects on "C chemical shifts were determined in a series of deuteriated cis-stilbene isotopomers. The magnitude and sign of these effects depend on the position and the number of deuterium atoms in the molecule. The variations in two-and three-bond effects were rationalized by ste
Exchange of amide protons with deuterium results in changes of 13 C chemical shifts for carbon atoms near the site of substitution (CH{N and N{C|O). There is a measurable decrease in the isotopic shifts of CH{N for cycloalkylacetamides as ring size increases from 3 to 8 and for lactams as ring size
