nitric oxide (NO) with (SCN)[sub2][sup [minus]], Br[sub2][sup [minus]], CO[sub2][sup [minus]], CO[sub 3][sup [minus]], and ethyl alcohol radicals were studied by the pulse radiolysis technique. The rate constants for the reaction of NO with these radicals are k[NO + (SCN)[sub2][sup [minus]]] = (4.3 [+-] 0.1) x 10[sup 9] M[sup [minus]1] s[sup [minus]1], k[NO + CO[sub2][sup [minus]]] = (2.9 [+-] 0

IR-spectroscopic investigations of light-inducedrearrangement reactions of nitrosooxymethane (CH3ONO3), nitrosooxyethane (CH3CH2ONO) and N,N-dimethylnitrosamine ((CH3)2NNO) in low-temperature rare-gas matrices have established that these molecules are transformed in two photolysis steps to the previously unknown C-nitroso compounds nitrosomethanol (CH2(OH)(NO)), 1-nitrosoethanol (CH3CH(OH)(NO)), and

Electrochemical analysis was used to probe the redoxchemistry of the complexes and assess their ease of reduction. All of the complexes displayed irreversible reduction and had low cathodic peak potentials. This suggests that the Co-tpa carrier system would provide a suitably inert framework to deliver the drugs to target sites intact yet would release the ligands upon reduction to the more labile Co(II)
