In this work. we treat the general case of an atom in a P-2 or P-3 electron
ic state reacting with a linear molecule in a (2)Pi, (2)Sigma or (3)Sigma e
lectronic state. We demonstrate that the spin-orbit selectivity of the rate
constant at low temperatures (T < 10 K) is associated with the different c
ontributions to the long-range intermolecular potential calculated in the s
pin-orbit basis set of the reactants. We give examples of applications to a
few reactions of astrophysical interest. (C) 1999 Elsevier Science B.V. Al
