The review is divided into four sections. We first consider the varied behavior of K n 2 S and n 2 D states in their chemical reactivity and physical characterization. We review the effect of orbital alignment of an electronically excited metal atom on the cross section of energy transfer or chemical reaction, and report the technique of a single supersonic jet employed to measure this effect on the Ca spin‐changing collision. We discuss the effects of temperature and isotopic mass on the distribution of rotational quantum number of the product MgH to identify the reaction mechanism of Mg( 1 P 1 ) + H 2 . The final concerns are the quantum yield, fine‐structure branching ratio and rate of collisional mixing for the K 2 P J doublets following photodissociation of KI at 193 nm.
