Abstract

Abstract : An approach to detect the velocity dependence of spin‐polarized H atoms has recently been developed. The technique, termed spin‐polarized hydrogen Rydberg time‐of‐flight (SPH‐RTOF), permits direct measurement of spin‐polarized H atoms born from a photodissociation or scattering event. The resulting H‐atom spin polarization can be fully described by three anisotropy parameters, all of which are captured in SPH‐RTOF. This review describes the approach in detail, provides a theoretical description that allows the experimentally obtained values to relate to the underlying dissociation dynamics of a molecule, and summarizes the first applications of SPH‐RTOF to the UV photodissociation of H(D)Br.
