Selective proton magnetic T₁ measurements on 2,6-dimethyl-1,4-dimethoxybenzene

Abstract

Selective T ₁ measurements as a function of temperature on 2,6-dimethyl-1,4-dimethoxybenzene show that the dipolar interaction is the only effective relaxation mechanism. The rotational diffusion of the molecule is anisotropic, and the internal methyl group rotation of the 4-methoxy group is slower than that of the other methyl groups.
