Transient Spectroscopy
Transient spectroscopy encompasses a powerful set of techniques for probing and characterizing the electronic and structural properties of short-lived excited states (transient states) of photochemically/photophysically relevant molecules. These states are accessed upon absorption of photons and essentially represent higher energy forms of the molecule, differing from the lowest energy ground s...
متن کاملAttosecond Transient Absorption Spectroscopy
Motion in the microcosm unfolds via the formation of wavepackets, resulting from a coherent superposition of quantum states. Pioneered by A. H. Zewail, nuclear motion in (bio-)molecules as well as the formation and rupture of chemical bonds have been accessed extensively by femtosecond (1 fs = 10 seconds) pump-probe spectroscopy. For these outstanding experiments, A. H. Zewail was awarded the N...
متن کاملNanofluidic Electrochemical Transient Spectroscopy
We introduce Nanofluidic Transient Spectroscopy as an electrochemical technique by utilizing potential-dependent adsorption of redox-active molecules on electrodes. Our approach is based on nanofluidic thin-layer cells, which consist of Pt electrodes embedded in opposing walls of a nanofluidic channel separated by a distance of 50 nm. Due to the high surface-to-volume ratio of the femtoliter-si...
متن کاملVisualizing transient dark states by NMR spectroscopy.
Myriad biological processes proceed through states that defy characterization by conventional atomic-resolution structural biological methods. The invisibility of these 'dark' states can arise from their transient nature, low equilibrium population, large molecular weight, and/or heterogeneity. Although they are invisible, these dark states underlie a range of processes, acting as encounter com...
متن کاملQuasiballistc Heat Conduction in Transient Grating Spectroscopy
Transient grating (TG) spectroscopy is an important experimental technique to measure mean free path (MFP) spectra using observations of quasiballistic heat conduction. To obtain MFP spectra, the measurements must be interpreted within the framework of the frequency-dependent Boltzmann transport equation (BTE), but previous solutions have restricted validity due to simplifying assumptions. Here...
