A review is presented of the use of vector correlations in the elucidation of photodissociation dynamics. Theoretical and experimental results are discussed for four correlations among the vectors E, the polarization direction of the photolysis light, ..mu.., the transition dipole of the parent molecule, v, the recoil velocity of the fragments, and J, the rotational angular momentum vector of a particular fragment. The four correlations to be described in detail are (1) the E-..mu..-v correlation, which results in an anisotropy of fragment recoil vectors in the laboratory frame; (2) the E-..mu..-J correlation, which results in an alignment of fragment rotational vectors in the laboratory frame; (3) the v-J correlation, which, although independent of the laboratory frame, can provide information on the alignment of the molecule relative to its velocity vector; and (4) the E-..mu..-(v-J) correlation, which combines all three effects. Other vector correlations are briefly considered through their relation to these four.
