Abstract
The complete results of analysis of the N.M.R. spectra of twelve 2,6-dimethyl-1-substituted benzenes are reported. The results are interpreted as evidence that the ability of the substituent to donate or withdraw electrons by resonance interaction with the benzene ring is a major factor in determining the position of absorption of the protons attached to the ring. The chemical shifts and coupling constants for nitroethylene are also reported.Keywords
