Trends in angle-resolved molecular photoelectron spectroscopy

Abstract

In this perspective article, main trends of angle-resolved molecular photoelectron spectroscopy in the laboratory up to the molecular frame, in different regimes of light-matter interactions, are highlighted with emphasis on foundations and most recent applications.

Topical Review: Extracting molecular frame photoionization dynamics from experimental data

“…Further details are discussed below, with a realistic example case forming the basis of section 4.1. (For further introductory discussion and examples of LF and MF PADs, see [11,15]; a recent review article can be found in [26]. )…”

“…The steps in the process are depicted in figure 4, which label's primary inputs as the 'AF/LF measurements', referring to the βu LM (t), and the ADMs A K QS (t) calculated for a grid of fluence and temperature values by solving the TDSE using the appropriate Hamiltonian for impulsive alignment [41,44]. The 'Alignment Retrieval' process requires solving the linear equations (26) for the CLM KQS using these primary inputs over the entire gird of ADMs, and comparing to the measured data to find the bets fit solution. This provides the vector C lab needed for the next step-solving the linear equations (28).…”

“…Reviews covering this class of experiment can be found in [13,16,26,[48][49][50]; some (representative) examples from the literature include:…”

“…In the current notation, the full expressions are written as per equation (26) for the LF/AF (cf equation ( 18…”

Attosecond imaging of photo-induced dynamics in molecules using time-resolved photoelectron momentum microscopy

“…It has been shown that time-resolved photoelectron spectroscopy can be applied to probe ultrafast electronic and nuclear molecular dynamics [43,[66][67][68][69][70][71]. However, angle-unresolved photoelectron spectra do not carry any spatial information about the dynamics, which is lost due to angle averaging.…”
