✦ Synopsis

170 NMR spectra were measured at natural abundance in DMSO for a series of 3-substituted pyridine l-oxides and their substituent chemical shifts were found to be correlated with ~ substituent constants and not with ApK a values.

## Abstract The values ^n^__J__ (^195^Pt, ^14^N) are shown to be measurable directly from the ^195^Pt spectrum for a variety of complexes containing nitrogen ligands. The sample temperature can play an important role in determining the width of the ^195^Pt signal. ^195^Pt chemical shifts for the co
