Vibrations Drive Ultrafast Intersystem Crossing of a Photoexcited Cr(III) Complex
Ying You, James K. McCusker, Arshad Mehmood +1
The Cr(III) coordination complex serves as an archetypical 3d transition metal system for probing ultrafast excited-state dynamics with spin conversion due to its intrinsic intersy…

Simulating Ultrafast Transient Absorption Spectra from First Principles using a Time-Dependent Configuration Interaction Probe
Arshad Mehmood, Myles C. Silfies, Andrew S. Durden +2
Transient absorption spectroscopy (TAS) is among the most common ultrafast photochemical experiments, but its interpretation remains challenging. In this work, we present an effici…
