Femtosecond dynamic of benzyl radical — •Markus Margraf1, Bastian Noller1, Thomas Schultz2, and Ingo Fischer1 — 1Institute of Physical Chemistry, University of Würzburg, Germany — 2Max Born Institute Berlin, Germany
The dynamic of benzyl radical was investigated by femtosecond time-resolved pump probe spectroscopy in a free jet. On the one hand we studied the dependence on pump wavelength (298 nm, 301 nm, 305 nm) at constant probe wavelength of 800 nm at all experiments and on the other hand we used different precursors for generating the benzyl radical. Toluene and 2-phenyl ethyl nitrite showed up as appropriate precursors. In all cases we observe a biexponential decay. The life times increased with pump wavelength.
