Remaining Unperturbed by the Vibrational Response: Probing Vibrational Coupling, Relaxation, and Solvent Effects with 2D IR Spectroscopy
… laser technique that is capable of probing the vibrational properties and dynamics down to the picosecond or even femtosecond timescales. This technique enables the analysis of vibrational couplings, energy redistribution pathways, and solvation dynamics in real time. The early chapters of this …

Photophysics of Phenylene Vinylene Polymers and Oligomers: The Influence of Nanocrystalline Domains
… of nanocrystalline domains in PPV and an exciton vibrational coupling theory shows that the vibronic peak distribution can be used as a measure of exciton delocalization. Transient emission spectroscopy shows that an initially localized exciton undergoes delocalization inside a single …

Multi-mode two-dimensional infrared spectroscopy of peptides and proteins
… IR to further resolve inter- and intramolecular couplings, relaxation pathways and structural kinetics in complex systems. Characterization of multi-mode spectra is first performed on model protein systems to reveal detailed information on the effects of solvation and structure on the amide …

Nanoscale thermal transport through solid-solid and solid-liquid interfaces
… by a combination of work of adhesion and vibrational coupling between the omega-group in the SAM and the liquid.

Probing Solvation Shell Dynamics of Organometallic Complexes via Two-Dimensional Infrared Spectroscopy
… FTIR spectroscopy shows the fundamental vibrational modes of a complex, yielding a spectrum that acts as a molecular fingerprint that allows for identification of chemical species and functional groups within a system. The one-dimensional nature of FTIR spectroscopy, however, occludes …

Nonlinear Light - Matter Interactions of Ultrafast High Intensity Laser Pulses
… with different response times. Electron cloud - vibrational coupling is also recorded in the “mother” states, which can be used to produce the Raman spectrum. Each n(t) thermalization stage is fitted to theoretical decay equations that give their rise and fall times.</p>

To Couple or not to Couple? Exploring Vibronic Coupling in Organic Semiconductors
… with nuclear motion. In particular, vibronic coupling governs many key performance metrics, including emission linewidth, radiative efficiency, charge separation rates, and non-radiative losses. The interaction between electronic excitations and vibrational degrees of freedom not only shapes …
