Unexpected shortening of the excited state lifetime of oxybenzone radical cation upon excitation of the band origin
Year: 2026
Type: article
Abstract: electronic transition was identified and excited-state lifetimes on the femtosecond timescale were estimated. Unexpectedly, the vibronic band origin exhibits a shorter lifetime than higher vibronic levels, attributed to an ultrafast excited-state proton transfer. In contrast, out-of-plane vibrational excitation disrupts hydrogen-bond directionality and suppresses this process, leading to longer excited-state lifetimes.
