摘要

A quantum control spectroscopy (QCS) approach using directly shaped UV excitation pulse is demonstrated. Ultrafast tailored pulses in the region of 310–335 nm are combined with transient absorption to investigate reactive pathways in the excited state of (2,2′-bipyridyl)-3,3′-diol BP(OH) $_2$. In particular, we apply QCS in the disentanglement of the competing excited-state intramolecular proton-transfer (ESIPT) channels of BP(OH)$_2$. Our results challenge parallel reactive pathways in the excited state and suggest a newer model based on an extremely fast sequential double ESIPT process.
