      Effect of molecular weight on the vibronic structure of a diketopyrrolopyrrole polymer 

      Hayes, Sophia C.; Pieridou, Galatia K.; Vezie, M.; Few, S.; Bronstein, H.; Meager, I.; McCulloch, I.; Nelson, J. (SPIE, 2016)
      Resonance Raman Spectroscopy (RRS) is employed in this study to examine the influence of molecular weight on the optical response of a diketopyrrolopyrrole polymer (DPP-TT-T) in solution. The vibronic structure observed ...

      The origin of the Fe IV = O intermediates in cytochrome aa 3 oxidase 

      Pinakoulaki, Eftychia; Daskalakis, Vangelis; Varotsis, Constantinos (2012)
      The dioxygen reduction mechanism in cytochrome oxidases relies on proton control of the electron transfer events that drive the process. Proton delivery and proton channels in the protein that are relevant to substrate ...

      Spin Crossover in Nitrito-Myoglobin as Revealed by Resonance Raman Spectroscopy 

      Lambrou, Alexandra; Ioannou, Androulla; Pinakoulaki, Eftychia (2016)
      The myoglobin (Mb) heme Fe-O-N=O and heme Fe-O-N=O/2-nitrovinyl species have been characterized by resonance Raman spectroscopy. In the heme Fe-O-N=O species, the bound nitrite ligand is removed by solvent exchange, thus ...
