“…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).…”

Methods for experimental reconstruction of molecular frame (MF) photoionization dynamics, and related properties - specifically MF photoelectron angular distributions (PADs) and continuum density matrices - are outlined and discussed. General concepts are introduced for the non-expert reader, and experimental and theoretical techniques are further outlined in some depth. Particular focus is placed on a detailed example of numerical reconstruction techniques for matrix-element retrieval from time-domain experimental measurements making use of rotational-wavepackets (i.e. aligned frame measurements) - the ``bootstrapping to the MF" methodology - and a matrix-inversion technique for direct MF-PAD recovery. Ongoing resources for interested researchers are also introduced, including sample data, reconstruction codes (the \textit{Photoelectron Metrology Toolkit}, written in python, and associated \textit{Quantum Metrology with Photoelectrons} platform/ecosystem), and literature via online repositories; it is hoped these resources will be of ongoing use to the community.

“…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.…”

We explore the novel capabilities offered by attosecond extreme ultraviolet and x-ray pulses that can be now generated by free-electron lasers and high-harmonics generation sources for probing photon-induced electron dynamics in molecules. We theoretically analyze how spatial and temporal dependence of charge migration in a pentacene molecule can be followed by means of time-resolved photoelectron microscopy on the attosecond time scale. Performing the analysis, we accurately take into account that an attosecond probe pulse leads to considerable spectral broadening. We demonstrate that the excited-state dynamics of a neutral pentacene molecule in the real space map onto unique features of photoelectron momentum maps.
