AI Article Synopsis
- Broadband visible transient absorption spectroscopy was utilized to study how excited state populations of 7-dehydrocholesterol react when excited by UV pulses with different linear chirps.
- The experiments revealed that the phase of the excitation pulse affects how quickly the excited state decays.
- Findings indicate that coherent mechanisms with interfering pathways could be used to influence the distribution of products formed from these excited states.
Article Abstract
Broadband visible transient absorption spectroscopy was used to characterize the excited state population of 7-dehydrocholesterol (provitamin D3, DHC) following excitation by UV pulses with systematically varied linear chirp. These experiments demonstrate that the phase of the excitation pulse can modify the observed excited state decay. The results suggest that coherent mechanisms involving multiple interfering pathways may be exploited to control branching between excited state pathways and manipulate product formation.
