Modern photoelectron imaging of negative ions did not receive much attention until the early 2000s. The field has since expanded into a vast area of research as the study of photodetachment from anions holds many advantages. The power behind photoelectron imaging lies in its ability to measure the photoelectron spectrum and spatial distribution of photoelectrons simultaneously, presenting information that can indirectly be related to the bonding structures of molecular systems. The photoelectron angular distribution can be related to the parent molecular orbital from which the photoelectron is detached both quantitatively and qualitatively through symmetry considerations, revealing important characteristics of the corresponding wavefunction. Here, we introduce an efficient algorithm for calculating PAD in the plane wave application. We also derive a dipole wave formalism to describe an outgoing electron in molecular anions with large dipole moments of the neutral core.
