Hydroxyl radical

Energy levels, transition frequencies and Einstein A coefficients were taken from the JPL catalogue. Note that the transition frequencies are only of spectroscopic accuracy for the file including hyperfine splitting. The collisional rate coefficients were taken from Offer et al. (1994) and were calculated for temperatures in the range from 15 to 300 K for collisions with both para-H2 and ortho-H2. At present no extrapolated rate coefficients are made available.
