Ultrafast internal conversion and photochromism in gas-phase salicylideneaniline
Myles C. Silfies, Arshad Mehmood, Grzegorz Kowzan +3
Salicylidenaniline (SA) is an archetypal system for excited-state intramolecular proton transfer (ESIPT) in non-planar systems. Multiple channels for relaxation involving both the…
Controlling rotationally-resolved two-dimensional infrared spectra with polarization
Grzegorz Kowzan, Thomas K. Allison
Recent advancements in infrared frequency combs will enable recording of coherent two-dimensional infrared spectra of gas-phase molecules with rotational resolution (RR2DIR). We de…
Theory of rotationally resolved two-dimensional infrared spectroscopy including polarization dependence and rotational coherence dynamics
Grzegorz Kowzan, Thomas K. Allison
Two-dimensional infrared (2DIR) spectroscopy is widely used to study molecular dynamics but it is typically restricted to solid and liquid phase samples and modest spectral resolut…
Momentum-Resolved Exciton Coupling and Valley Polarization Dynamics in Monolayer WS
Alice Kunin, Sergey Chernov, Jin Bakalis +8
Coupling between exciton states across the Brillouin zone in monolayer transition metal dichalcogenides can lead to ultrafast valley depolarization. Using time- and angle-resolved…
Broadband ultraviolet-visible frequency combs from cascaded high-harmonic generation in quasi-phase-matched waveguides
Jay Rutledge, Anthony Catanese, Daniel D. Hickstein +3
High-harmonic generation (HHG) provides short-wavelength light that is useful for precision spectroscopy and probing ultrafast dynamics. We report efficient, phase-coherent harmoni…
Broadband cavity-enhanced ultrafast spectroscopy
Myles C. Silfies, Grzegorz Kowzan, Neomi Lewis +1
Broadband ultrafast optical spectroscopy methods, such as transient absorption spectroscopy and 2D spectroscopy, are widely used to study molecular dynamics. However, these techniq…
