RESUMO
Electrochemical and spectrophotometric methods are described for measuring the rate of nitric oxide (NO) dissociation (k(NO)) from coordination compounds. Electrochemical methods based on double-potential step chronoamperometry and rotating ring-disc electrode voltammetry techniques proved to be suitable for measuring NO dissociation from 0.03 to 4.0 s(-1). The spectrophotometric method using an ancillary ligand as a colorimetric indicator is illustrated on measuring k(-NO)=0.002 s(-1). This methodology is limited only by the rate of the ancillary ligand substitution.
