Application Example How to Combine Different EPR Techniques

At this point, it would be interesting to compare the temperature behavior of MbNO with that of oxygenated Mb. However, oxygenated heme proteins 

Not only can the ferrous Mb bind NO, also its related Fe(III) form binds NO, giving rise to an EPR-silent complex. Upon illumination (photolysis) of ferric MbNO EPR-active products become detectable [67]. Upon photolysis at low
