We report calculated Einstein coefficients for the pure-rotation and vibration-rotation transitions of OH(X2Pi), with particular emphasis on those involving high-lying rotational levels. Coefficients are reported for rotational levels ranging from N = 42 (v = 0) to N = 9 (v = 9). The pure-rotation coefficients are the first to be reported in the literature. The effects of the centrifugal distortion are explicitly accounted for in these calculations, and individual spin-sublevel-specific coefficients are reported. Centrifugal distortion in this work was accounted for assuming an expression for rotational kinetic energy appropriate in the Hund's case (b) limit. Comparison with otherwise similar calculations by Nelson et al. (1989, 1990), which incorporate the effects of incomplete spin uncoupling on the rotational kinetic energy, shows that this approximation results in insignificant errors for N-prime not less than 10.
