We also present a preliminary account of femtosecond X-ray absorption studies on MbNO, pointing to the presence of more than one species formed upon photolysis.Chemistry, PhysicalChemistrystructural dynamicsmolecular-dynamicsresonance ramancarbon-monoxideligand-bindingcytochrome-cspin-statevibrational-relaxationtransient absorptionmyoglobintext::journal::journal article::research article
