Photosynthesis is a vital process that forms the basis of most life and energy sources on the planet. The knowledge of the underlying mechanisms of charge and energy transfer involved in this process can be used to develop artificial light-harvesting systems and biofuels, helping us to meet our own energy needs. In this talk, I will discuss how we use fluorescence-detection-based two-dimensional electronic spectroscopy (F-2DES) to study the energy transfer in light-harvesting (LH2, in particular) complexes present in photosynthetic purple bacteria. Due to long acquisition times, photobleaching effects during the 2D measurements can distort the features of the acquired spectra. Motivated by the desire to reduce these effects without sacrificing the signal-to-noise ratio (SNR), we have adapted a rapid-scanning approach to record the linear spectra of the complexes in question. I will discuss the technique and results from the same. Extending this rapid-scanning technique to F-2DES promises reduced acquisition times and improved SNR for the 2D spectra.
