Optimization of pump–probe signal requires a complete understanding of how signal scales
with experimental factors. In simple systems, signal scales quadratically with molar …

Transient absorption (TA) spectroscopy is an invaluable tool for determining the energetics
and dynamics of excited states. When pump intensities are sufficiently high, TA spectra …

Fluorescence-detected multidimensional electronic spectroscopy (fMES) promises high
sensitivity compared to conventional approaches and is an emerging spectroscopic …

We demonstrate an approach to two-dimensional electronic spectroscopy (2DES) that
combines the benefits of shot-to-shot detection at high-repetition rates with the simplicity of a …

A solution to Maxwell's equations in the three-dimensional frequency domain is used to
calculate rephasing two-dimensional Fourier transform (2DFT) spectra of the D2 line of …

Multiexciton absorption cross sections are important for analysis of a number of experiments,
including multiple exciton generation and stimulated emisson. We present a rigorous …

We demonstrate a femtosecond pump–probe spectrometer that utilizes a white light
supercontinuum as input and relies on mutual synchronization of the laser repetition rate …

Understanding the transient absorption dynamics of IR-780 infrared dye is important since it
is extensively used in in vivo imaging and phototherapy treatments. It is widely used in …

In experiments with high photon flux, it is necessary to rapidly remove the sample from the
beam and to delay re-excitation until the sample has returned to equilibrium. Rapid and …

4 Excited States of Single-Stranded DNA Revealed by Femtosecond Transient slow,
nonradiative decay channels. This chapter provides a detailed discussion of the …
