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

## Abstract A new class of compounds, the 2โhydroxythioacetophenones, and related compounds have recently been synthesized. The hydrogenโbond system has been characterized by NMR chemical shifts and deuterium isotope effects on these as well as by DFT calculations. Use of solidโstate ^13^C NMR has
Deuterium-induced chemical shift differences on the 13C (DIS) are reported for a series of Schiff bases of salicylaldehydes, l-(phenyliminomethyl)naphthalen-2-ol and 4-chloro-1,7-phenanthrolin-l0-ol. Provided that corrections for the hydrogen donor atom and diamagnetic effects of the surrounding gro
