Photoelectron angular distributions.
TLDR
In this review, which is aimed at experimentalists, simple expressions for photoelectron angular distributions (PADs) in various experimental geometries are given and their applications explained.Abstract:
Angle-resolved photoelectron spectroscopy has been performed for more than 70 years in various guises, but recently its potential to help solve in detail problems in the photoionization dynamics and intramolecular dynamics of gas-phase molecules has been recognized. One key development has been the design of experiments in appropriate geometries to extract information that pertains to the molecular frame, another has been the development of imaging spectrometers, and a third is the use of ultrafast lasers to cause photoionization. In this review, which is aimed at experimentalists, simple expressions for photoelectron angular distributions (PADs) in various experimental geometries are given and their applications explained.read more

Characterization of spectral diffusion from two-dimensional line shapes
TL;DR: A number of quantitative measures of frequency fluctuations and spectral diffusion through the analysis of two-dimensional line shapes are described, identical to the system's frequency correlation function and independent of population relaxation in the limit of a short time approximation for the 2D response.

Asymmetry in Photoelectron Emission from Chiral Molecules Induced by Circularly Polarized Light
TL;DR: In photoionization of free, unoriented chiral molecules with circularly polarized radiation, a significant circular dichroism has been observed in the photoelectron angular distribution, which leads to an asymmetry in the momentum transfer to the photoions.
