The protons in the -CH/sub 2/D groups of a deuterotoluene are 0.015 plus or minus 0.002 ppm more shielded than are those in the -CH/sub 3/ group of deuterium-free toluene or p-deuterotoluene. The magnitude of the effect for protons is only about 1/40 of that for fluorine nuclei, but the direction of the shift indicates a greater electron-donated power for deuterium than for hydrogen. The equipment and procedures for these experiments are described, and preparation of the reagents is discussed. (J.R.D.)
