The sensitivity of rotatory detection is determined to be 0.10 milli-degrees for a measurement time of only one second and an interaction length of 250 µm. Its suitability for femtosecond studies is demonstrated in a non-resonant two-photon photodissociation experiment.}, language = {en} } @article{RuetzelKullmannBubacketal.2013, author = {Ruetzel, S. and Kullmann, M. and Buback, J. and Nuernberger, P. and Brixner, T.}, title = {Exploring higher-lying electronic states of a molecular switch by coherent triggered-exchange 2D electronic spectroscopy}, series = {EPJ Web of Conferences}, volume = {41}, journal = {EPJ Web of Conferences}, number = {05001}, doi = {10.1051/epjconf/20134105001}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-129117}, year = {2013}, abstract = {We use pump-repump-probe transient absorption spectroscopy to investigate the role of higher-lying electronic states in the photochemistry of a molecular switch.
