TLDR
The origins of electronic angular momentum polarization are introduced and experimental and theoretical methods for the measurement or calculation of atomic orientation and alignment parameters described.Abstract:
The angular momentum polarization of atomic photofragments provides a detailed insight into the dynamics of the photodissociation process. In this article, the origins of electronic angular momentum polarization are introduced and experimental and theoretical methods for the measurement or calculation of atomic orientation and alignment parameters described. Many diatomic photodissociation systems are surveyed, in order to provide an overview both of the historical development of the field and of the most state-of-the-art contemporary studies.read more

Imaging atomic orbital polarization in photodissociation.
TL;DR: A new, fully quantum theory was required for interpretation of angular momentum polarization in atoms, and the foundation for this theory was established in a paper in 1994 by Siebbeles et al.
Journal ArticleDOI
A Stark future for quantum control.
TL;DR: An overview of developments using the nonresonant dynamic Stark effect within the fields of time-resolved molecular dynamics and quantum control, with particular emphasis on the notion that "dynamics" and "control" are not distinct disciplines.

Photodissociation dynamics of OCS at 248nm: The S(D21) atomic angular momentum polarization
TL;DR: In this article, speed distributions, speed dependent translational anisotropy parameters, angular momentum alignment, and orientation are reported for the channel leading to S(D21) in CO coproducts.

Collisional depolarization of OH(A) with Ar: Experiment and theory.

TL;DR: Simulation of the experimental beat amplitudes, using theoretical calculations presented in the preceding paper, reveals that depolarization of OH(A) by Ar has a rate constant comparable to, if not larger than, that for energy transfer.

Laser detection of spin-polarized hydrogen from HCl and HBr photodissociation: Comparison of H- and halogen-atom polarizations
TL;DR: Good agreement occurs despite the fact that the current experiments photodissociate molecules at 295 K, whereas previous measurements were conducted at rotational temperatures of about 15 K, suggesting that further theoretical investigations are required.
