The theoretically derived dipole moment function of OH( X2Π) obtained by Stevens Das, Wahl, Neumann, and Krauss is used to calculate the absolute intensities of the vibrational-rotational transitions of the OH Meinel bands. The calculations take full account of the spin uncoupling and vibration-rotation coupling which markedly influence the radiative transition probabilities. The effect of lambda-doubling on the vibrational transitions is analyzed and generally found to be negligible. Results are tabulated for ∆ v = v' - v″ ranging from the fundamental transitions ∆ v = 1 to the ∆ v = 5 overtone, for v' = 1-9 and J' = 0.5 - 15.5. A comparison is made with available data, and various features of the OH spectrum are examined that are of aeronomical and experimental interest. Thermally averaged emission rates are presented for ∆ v = 1-5, and the validity of the rotational temperatures commonly derived from experimental intensity distributions is questioned.
