摘要：

(Graph Presented) Trust is good, control is better: In thermal processes in which the interconversion of reactant conformers R1/2 is faster than the reaction itself, selectivity can be tailored by modulating the energy barriers of competing reaction paths. Ultrafast photoexcitation promotes separate conformers to different regions of the potential energy surface, where the wave packet may reach different conical intersections CI1/2, giving rise to product selectivity (P1/2). © 2008 Wiley-VCH Verlag GmbH & Co.
