Abstract
Heterolytic and homolytic S-NO bond dissociation energies are determined in acetonitrile at 25 degrees C by using titration calorimetry and electroche mical measurements with a well-designed thermodynamic cycle. The results su ggest that S-NO compounds in vivo may release NO in a manner of homolytic b ond dissociation. Other effects that influence the bond energies are also d iscussed.
