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

Ultrafast photochemical reactions in liquids occur on similar or shorter time scales compared
to the equilibration of the optically populated excited state. This equilibration involves the …

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 …

Perylene bisimides (PBIs) have received great attention in their applicability to
optoelectronics. Especially, symmetry-breaking charge separation (SB-CS) in PBIs has been …

Electron transfer reactions facilitate energy transduction and photoredox processes in
biology and chemistry. Recent findings show that molecular vibrations can enable the …

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 …

Photoinduced electron transfer (ET) is a cornerstone of energy transduction from light to
chemistry. The past decade has seen tremendous advances in the possible role of quantum …

Femtosecond laser pulses readily produce coherent quantum beats in transient–absorption
spectra. These oscillatory signals often arise from molecular vibrations and therefore may …

Broadband optical pump and compressed white light continuum probe were used to
measure the transient excited-state absorption, ground-state bleach, and stimulated …

The role of molecular vibration in photoinduced electron transfer (ET) reactions has been
extensively debated in recent years. In this study, we investigated vibrational wavepacket …
