Abstract: A series of imidazole NO spin probes and their reaction intermediates were studied with AM1 quantum chemistry calculations. The geometrical structure, the electronic structureand the spin distribution were calculated in details. We discussed the effect of the substituenton the characters of the spin probes and the Possible reaction course of spin probes with NO theoretically.
