Crossings of electronic potential energy surfaces in nuclear configuration space, known as
conical intersections, determine the rates and outcomes of a large class of photochemical …

Conspectus Femtosecond spectroscopy has revealed coherent wave packet motion time
and time again, but the question as to whether these coherences are necessary for reactivity …

Excited-state relaxation of cis-and trans-stilbene is traced with femtosecond stimulated
Raman spectroscopy, exploiting S n← S1 resonance conditions. For both isomers, decay in …

Photochemical reactions are mediated by conical intersections (CI), which are difficult to
directly probe and characterize. To gain insight into CIs, two-dimensional femtosecond …

First demonstrated in 1994, femtosecond stimulated Raman scattering (FSRS) has gained
popularity since the early 2000s as an ultrafast pump–probe vibrational spectroscopy …

Mapping out multidimensional potential energy surfaces has been a goal of physical
chemistry for decades in the quest to both predict and control chemical reactivity. Recently a …

4-(Dimethylamino) benzonitrile (DMABN) has been one of the most studied photoinduced
charge-transfer (CT) compounds for over 50 years, but due to the complexity of its excited …

Electronic and vibrational correlations report on the dynamics and structure of molecular
species, yet revealing these correlations experimentally has proved extremely challenging …

Two-dimensional femtosecond stimulated Raman spectroscopy (2D-FSRS) is used to probe
