The [Formula: see text] values for 3-pentanone, 2-butanone, and 3-methyl-2-butanone have been determined from chemical shift data. The values (−7.6, −7.1, and −7.2, respectively) are in good agreement with those previously determined for aliphatic ketones by use of ultraviolet–visible and Raman spectroscopy.

Marked differences in chemical shift of the signal for the α proton in indole and substituted indoles occur when spectra are obtained in non-polar and polar solvents. In contrast, using polar and non-polar solvents, only small differences are observed in the chemical shift of the signal for the β proton in indoles. The utility of the solvent effect on the chemical shift to distinguish between α and β substitution of the indole nucleus is pointed out.
