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

Two-dimensional electronic spectroscopy (2DES) reveals connections between an optical
excitation at a given frequency and the signals it creates over a wide range of frequencies …

2D infrared (IR) spectroscopy is a cutting-edge technique, with applications in subjects as
diverse as the energy sciences, biophysics and physical chemistry. This book introduces the …

Multidimensional Coherent Optical Photocurrent Spectroscopy (MD-COPS) is implemented
using unstabilized interferometers. Photocurrent from a semiconductor sample is generated …

Ultrafast two-dimensional infrared spectroscopy (2D IR) has been advanced in recent years
