✦ Synopsis

Abstract

Chemical shifts for tritons in ortho, meta and para positions in toluene have been determined using a 64 MHz tritium NMR spectrometer. The order of shift is meta>para>ortho, whereas the calculated shift order for protons is meta>ortho>para.

## Abstract Chemical shifts of the ring protons are determined by ^1^H NMR of 99% deuterated toluene. At low temperatures the deuterons relax rapidly, yielding sharp ^1^H peaks for the __ortho__, __meta__ and __para__ protons. These are compared with shifts obtained by other methods.
