Femtosecond pump probe spectroscopy for the study of energy transfer of light-harvesting complexes from extractions of spinach leaves. South African Journal of Science, Vol. 105(9/10), pp 376-3860038-2353http://hdl.handle.net/10204/3689Copyright: 2009 Academy of Science of South AfricaMeasurements of ultrafast transient processes, of temporal durations in the picosecond and femtosecond regime, are made possible by femtosecond pump probe transient absorption spectroscopy. Such an ultrafast pump probe transient absorption setup has been implemented at the CSIR National Laser Centre and has been applied to investigate energy transfer processes in different parts of photosynthetic systems. In this paper, researchers report on the first results obtained with Malachite green as a benchmark. Malachite green was chosen because the lifetime of its excited state is well known. Researchers also present experimental results of the ultrafast energy transfer of light-harvesting complexes in samples prepared from spinach leaves. Various pump wavelengths in the range 600–680 nm were used; the probe was a white light continuum spanning 420–700 nm. The experimental setup is described in detail in this paper. Results obtained with these samples are consistent with those expected and achieved by other researchers in this field.enPump probe spectroscopyFemtosecond laserUltrafast spectroscopyTransient absorptionLight-harvesting complex IIMalachite greenArticleOmbinda-Lemboumba, S., Du Plessis, A., Sparrow, R., Molukanele, P., Botha, L., Rohwer, E., ...
