DOI: 10.1016/j.jmr.2017.02.007
Abstract: Electron Nuclear DOuble Resonance (ENDOR) is based on the measurement of nuclear transition frequencies through detection of changes in the polarization of electron transitions. In Davies ENDOR, the initial polarization is generated by a selective… read more here.

DOI: 10.1021/jacs.9b04474
Abstract: We have shown that the key state in N2 reduction to two NH3 molecules by the enzyme nitrogenase is E4(4H), the "Janus" intermediate, which has accumulated four [e-/H+] and is poised to undergo reductive elimination… read more here.

DOI: 10.1039/c7dt01354j
Abstract: Activated bleomycin (ABLM) is a drug-Fe(iii)-hydroperoxide complex kinetically competent in DNA attack (via H4' abstraction). This intermediate is relatively stable, but its spontaneous conversion to ferric bleomycin (Fe(iii)·BLM) is poorly characterized because no observable intermediate… read more here.
