摘要：

Lights, spectrometer, action: Crucial information about the detailed shape of the potential-energy surface in the vicinity of the transition state is obtained from the Fano resonances in the photodissociation cross-section of diazirine in the S1 state. The excitation along the asymmetric C-N stretching mode accelerates the ringopening reaction, suggesting that two C-N bonds of the excited diazirine break in a stepwise manner (see scheme). figure presented" © 2010 Wiley-VCH Verlag GmbH & Co.
