Abstract
An improved maleimide spin label, namely, N-(.sup.15 N-oxyl-2,2,6,6-tetra-methyl-4-piperidinyl-d.sub.17) maleimide is provided for EPR spectroscopic investigations of biomedically relevant problems. Isotopic substitution of nitrogen-15 in the N--O bond and deuterium in the methyl groups (-CD.sub.3) and in all positions of the piperidine ring results in simplification of the EPR spectrum, greatly improved resolution, and a marked increase in signal intensity.
