✦ Synopsis

Abstract

Chemical shifts and line broadenings induced by a series of lanthanide dipivaloylmethanates Ln(dmp)~3~ on the ^17^O NMR signal of methanol have been measured. The best high‐field shift reagents are those containing the cations Tb^+3^ and Dy^+3^; very large shifts have been observed for even quite low concentrations of reagent. The shift reagents are able to discriminate between different oxygen functions and can, in principle, be used for line assignments.

## Abstract ^13^C NMR shifts of 54 chalcones and their thiophene and furan analogues are analyzed by principal component analysis. Thus, a mathematical model is derived for the variation of the carbon shifts in each of seven classes. Two component models are found to be adequate by cross‐validation
