## Abstract A new class of compounds, the 2โ€hydroxythioacetophenones, and related compounds have recently been synthesized. The hydrogenโ€bond system has been characterized by NMR chemical shifts and deuterium isotope effects on these as well as by DFT calculations. Use of solidโ€state ^13^C NMR has

The interesting deuterium isotope e โ€ ects of gossypols have been reinvestigated and the very large two-bond isotope e โ€ ect, 2DC-6(OD), is ascribed to electric รeld e โ€ ects. Common to the investigated compounds is the presence of intramolecular hydrogen bonds. A feature strongly related to the streng

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

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
