How do we look at ultra fast changes in molecules excited by light? • At the University of Auckland in the Photon Factory we use Transient Absorption Spectroscopy to to take snapshots of the molecules changing on the timescale of femtoseconds (10^-15 seconds) using lasers. • Learn how the spectrometer works and how we use it to study photochemical and photophysical interactions such as degradation of molecules in priceless artwork and new molecules for solar energy harvesting. • This video was made for the RSC film competition. • http://my.rsc.org/chemcareers/cwcompe... • Go to the Photon Factory website to find out more about TrA • http://photonfactory.auckland.ac.nz/
