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 …

Conical intersections play a critical role in excited-state dynamics of polyatomic molecules
because they govern the reaction pathways of many nonadiabatic processes. However …

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

This account places a particular emphasis on recent progress in the theory and its
applications of nonadiabatic electron dynamics in chemical science. After a brief description …

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

Photophysical and photochemical processes are ruled by the interplay between transient
vibrational and electronic degrees of freedom, which are ultimately determined by the …

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

We report two-dimensional electronic spectroscopy (2DES) experiments on the bacterial
reaction center (BRC) from purple bacteria, revealing hidden vibronic and excitonic …

The negatively charged nitrogen vacancy (NV) center in diamond is an optically accessible
material defect with a unique combination of spin and optical properties that has attracted …

The coherent vibrational dynamics of Au144 (SC8H9) 60, obtained from femtosecond time-
resolved transient absorption spectroscopy, are described. Two acoustic modes were …
