Intersystem crossing (ISC), formally forbidden within nonrelativistic quantum theory, is the
mechanism by which a molecule changes its spin state. It plays an important role in the …

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

Since the discovery of quantum beats in the two-dimensional electronic spectra of
photosynthetic pigment-protein complexes over a decade ago, the origin and mechanistic …

Singlet fission, a multistep molecular process in which one photon generates two triplet
excitons, holds great technological promise. Here, by applying a combination of transient …

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

We developed pulse-shaper-assisted coherent two-dimensional (2D) electronic
spectroscopy in liquids using fluorescence detection. A customized pulse shaper facilitates …

The finite spectral line width of an ensemble of CdSe nanocrystals arises from size and
shape inhomogeneity and the single-nanocrystal spectrum itself. This line width directly …

Accurate description of finite-temperature vibrational dynamics is indispensable in the
computation of two-dimensional electronic spectra. Such simulations are often based on the …

During the past two decades, two-dimensional electronic spectroscopy (2DES) and related
techniques have emerged as a potent experimental toolset to study the ultrafast elementary …

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 …
