✦ Synopsis

Abstract

The addition of iodine to pyridine not only causes appreciable changes in the ^13^C chemical shifts but also a marked reduction in spin‐lattice relaxation times. The effect at the γ‐carbon is larger than at the α‐ and β‐carbons. This is consistent with the formation of a pyridine‐iodine complex with a preferential tumbling about the C‐γNI axis. Elementary theory is applied to approximate the tumbling ratio.
