Abstract
A general method is provided to calculate chemical shifts for protons attached to sp3 carbons (methyl, methylene and methine). the approach is similar to rules developed by J. N. Shoolery in 1959. His rules are extended to allow calculations of proton chemical shifts in molecules that have multiple substituents within three carbons of the calculated proton chemical shifts.
