Reactions of ground-state and electronically excited sodium atoms with methyl bromide and molecular chlorine

The reactions of ground- and excited-state Na atoms with methyl bromide (CH3Br) and chlorine (Cl2) have been studied by using the crossed molecular beams method. For both reactions, the cross sections increase with increasing electronic energy. The product recoil energies change little with increasing Na electronic energy, implying that the product internal energies increase substantially. For Na + CH3Br, the steric angle of acceptance opens with increasing electronic energy
