      Analysis of the excited-state absorption spectral bandshape of oligofluorenes 

      Hayes, Sophia C.; Silva, C. (2010)
      We present ultrafast transient absorption spectra of two oligofluorene derivatives in dilute solution. These spectra display a photoinduced absorption band with clear vibronic structure, which we analyze rigorously using ...

      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 ...
