Abstract

The relaxation behavior of a coupled AMX spin system (cinnamic acid and methyl cinnamate) has been investigated. The description is based on the “magnetization modes” formalism proposed by Grant. The time evolution of the magnetization, which determines the relaxation behavior, is measured via inversion recovery experiments. The diffusion constants as well as the random fields are fitted by means of a least-squares procedure. To gain verification for these values a cross-check with different independent measurements as well as calculations based on the frictional description of the molecules has been employed.
