A theory and method for a matrix-based reconstruction of molecular frame (MF) photoelectron angular distributions (MFPADs) from laboratory frame (LF) measurements (LFPADs) is developed and basic applications are explored. As with prior studies of MF reconstruction, the experimental side of this protocol is based upon time-resolved LF measurements in which a rotational wavepacket is prepared and probed as a function of time via photoionization, followed by a numerical reconstruction routine.

Discrimination of Excited States of Acetylacetone through Theoretical Molecular-Frame Photoelectron Angular Distributions
Photoelectron angular distribution (PAD) in the laboratory frame for randomly oriented molecules is typically described by a single anisotropy parameter, the so-called asymmetry parameter. However,

Time-resolved photoelectron angular distributions as a probe of intramolecular dynamics: Connecting the molecular frame and the laboratory frame
A formalism is presented in which the laboratory frame photoelectron angular distribution (PAD) is expressed as a convolution of the molecular frame PAD with the laboratory frame molecular axis
The quantitative determination of laser-induced molecular axis alignment.
TLDR
A general maximum-likelihood classification procedure for non-adiabatic numerical alignment simulations with free parameters that employs experimental data from an alignment-dependent probe and delivers the most probable molecular frame angular dependence of the probe and the most likely laboratory frame axis alignment distribution of the sample.
Molecular frame image restoration and partial wave analysis of photoionization dynamics of NO by time-energy mapping of photoelectron angular distribution.
TLDR
The benchmark system of molecular photoionization dynamics, the (1+1{'}) two-photon ionization of NO via the A state, is investigated using the time-energy mapping of the photoelectron angular distribution in a laboratory frame and the l hybridization of p waves is identified.
Molecular Frame Reconstruction Using Time-Domain Photoionization Interferometry.
TLDR
XUV photoionization of impulsively aligned molecular targets (N_{2}) is used to provide a time-domain route to "complete"photoionization experiments, in which the rotational wave packet controls the geometric part of the photoionized interferometer.
Time-resolved photoelectron spectroscopy: from wavepackets to observables.
TLDR
A conceptual framework for time-resolved photoionization measurements is presented, together with discussion of relevant theory for the different aspects of TRPES, and simple models are used to illustrate the theory and key concepts are amplified by experimental examples.

Imaging polyatomic molecules in three dimensions using molecular frame photoelectron angular distributions.
TLDR
It is found that at low photoelectron energies the molecule is effectively imaged by the focusing of photoelectrons along bond directions.
Electron localization following attosecond molecular photoionization
TLDR
Attosecond pump–probe strategies are established as a powerful tool for investigating the complex molecular dynamics that result from the coupling between electronic and nuclear motions beyond the usual Born–Oppenheimer approximation.
