A recent paper in this journal [Y. B. Band e t a l., J. Chem. Phys. 8 4, 3762 (1986)] reported parameters describing orientation and alignment produced, in an axial recoil limit, by one photondissociation of diatomic molecules. Reported also were values, applicable to the resonance transitions of the alkali atoms, for orientation and alignment depolarization coefficients. Most of the numerical values reported for the coefficients were incorrect, in some cases by as much as a factor of 2. We report a tabulation of correct depolarization coefficients applicable to the resonance transitions of common alkali isotopes. Further, the coefficients depend on measured hyperfine splittings and radiative lifetimes. Thus, uncertainties in the coefficients reflecting those in measured quantities are also presented. An application of our results to a recent Na2photodissociation experiment [E. W. Rothe e t a l., Chem. Phys. Lett. 2 2, 100 (1980)] is also made.
