Abstract

Two commonly used hydrophobic and hydrophilic spin traps for NO, namely Fe2+(DETC)2 and Fe2+(MGD)2, respectively, were analyzed via EPR spectroscopy. EPR spectra of trapped NO, together with field position standards, were recorded both in the frozen state and at room temperature. We present a detailed characterization of the EPR spectra of the above paramagnetic NO complexes, concerning g-value, hyperfine splitting and linewidths. This study also provides spectroscopic data required to develop a quantitative and sensitive detection system for nitric oxide both in hydrophobic and hydrophilic aqueous media.
