Over the past few decades, coherent broadband spectroscopy has been widely used to
improve our understanding of ultrafast processes (eg, photoinduced electron transfer, proton …

Femtosecond nonlinear spectroscopy is the main tool for the time-resolved detection of
photophysical and photochemical processes. Since most systems of chemical interest are …

Abstract Design-specific control over the transitions between excited electronic states with
different spin multiplicities is of the utmost importance in molecular and materials chemistry …

The superposition of quantum states drives motion on the atomic and subatomic scales, with
the energy spacing of the states dictating the speed of the motion. In the case of electrons …

Femtosecond optical pump–probe spectroscopy with 10 fs visible pulses is employed to
elucidate the ultrafast carrier dynamics of few-layer MoS2. A nonthermal carrier distribution …

The kinetics of the primary event in vision have been resolved with the use of femtosecond
optical measurement techniques. The 11-cis retinal prosthetic group of rhodopsin is excited …

Photodissociation induced by the absorption of single photons permits the detailed study of
molecular dynamics such as the breaking of bonds, internal energy transfer and …

Hybrid organic–inorganic perovskites have attractive optoelectronic properties including
exceptional solar cell performance. The improved properties of perovskites have been …

The halide ions of organic-inorganic hybrid perovskites can strongly influence the interaction
between the central organic moiety and the inorganic metal halide octahedral units and thus …

Abstract Pump–supercontinuum-probe (PSCP) spectroscopy with femtosecond time
resolution is developed theoretically and experimentally. The connection to previous …
