摘要：

Seven new spin-labeled copper salicylaldimines have been prepared with electron-donating and-withdrawing groups on the salicylaldehyde ring. Resolved electron-electron coupling was observed in the room-temperature solution EPR spectra with values ranging from 5.5 G (0.000 53 cm-1) to 25.7 G (0.00247 cm-1). Values of J are dependent on temperature and solvent and on the ring substituent. © 1979, American Chemical Society. All rights reserved.
