Oxygen and imaging, a perfect match — •David Parker — Radboud University, Department of Physics, FNWI-IMM-MLF, NIjmegen, The Netherlands
Molecular oxygen, O2, is fascinating molecule. Despite this, a full understanding of the photodynamics of molecular oxygen is lacking due to the complex electronic structure and the forbidden nature of almost all optical transitions of O2. Over the past decade our group has been able to reveal many new aspects of O2 photodynamics due in part to the development and application of the velocity map imaging technique. In this talk I will highlight our past work on the photodissociation of: O2 super-excited states , the Herzberg continuum6 of O2, singlet oxygen b-state, the Schumann-Runge continuum, and O2-isoprene clusters. I will mainly describe new work on the photodissociation of the singlet oxygen a 1Δg -state. Velocity map imaging will be shown to be particularly well-matched to the study of O2 photodynamics.
