Accurate line positions, transition probabilities and oscillator strengths for the 0-1, 1-2, and 0-2 rotation-vibration bands of the hydroxyl ion are obtained. Computed emission cross sections of the microwave frequencies: OH(+) (nu1 = 123.544 GHz) and OH(+) (nu2 = 60.8545 GHz) indicate that the OH(+) radical is expected to be present in astronomical sources whose state temperatures are not greater than about 60 K. On the basis of binary gas phase reactions the formation and depletion of OH(+) in the interstellar space are also discussed.
