A search for a dialkylaminyl radical which rearranges at a rate suitable for study by kinetic EPR spectroscopy has shown that cyclobutyl-n-propylaminyl is such a species.This radical undergoes ring opening, and the rate constant for this process can be represented by log (k_r/s^-1) = (12.8+/-1.5) - (10.5+/-1.5)/θ, where θ = 2.3RT kcal/mol.
