Abstract

Velocity-aligned, superthermal atoms generated via polarised molecular photodissociation have been used to investigate vector correlations of bimolecular reactions. Doppler-resolved, polarised laser-probe techniques can measure correlations between k (the reagents' relative-velocity vectors), k' (the reaction products' velocity vectors) and J' (the products' rotational angular momenta) using a simple laboratory to centre-of-mass frame transformation. This approach to the study of the dynamical stereochemistry of chemical reactions is illustrated by two examples, O(1D)+N2O-->NO+NO and O(3P)+CS-->CO+S.
