Figure 8.
Electronic absorption (top, black) and MCD (bottom, red) spectra of RTNO prepared via reaction of NO with complex 1 at ambient temperature. The absorption spectrum was measured in CH2Cl2. The MCD spectrum was obtained for a frozen, glassy solution in 1:1 (v/v) CH2Cl2:butyronitrile at a temperature of 4 K and a magnetic field of 7 T. Inset: X-band EPR spectrum (blue line) of RTNO in frozen CH2Cl2. Parameters: frequency = 9.497 GHz; power = 0.5 mW; modulation amplitude = 1.0 G; T = 77 K.
