Abstract
In many of the reactions of the alkali metals with the halogens the reacting system changes from a homopolar to a polar state, or vice versa. The possibility of a restriction on this change is considered, and it is concluded that there will be a serious restriction only for some of the atomic reactionsM+X→MX, which are of little importance. The crossing points between the polar and homopolar states for the reactionsM2+X→MX+M M+X2→MX+X are drawn in so close that the interaction is large enough to insure transition. Due to the threefold degeneracy of the initial state of b (which arises because X is in a P state) this reaction has the possibility of leading directly to the excitation of the M atom which is formed. The nature of the potential surfaces for this process are considered. The process first suggested by Polanyi, the excitation of M atoms by vibrationally excited MX molecules, is discussed. This process is possible because of a crossing of the two lowest polar states for the M2X system. These two surfaces cross for a certain isosceles triangular configuration. Reacting systems thus easily go from the lowest to the second state in this region.
