The Wulf bands of oxygen in the 240-290 nm spectral region are caused by collision-induced absorption of the Herzberg III (A'(3)Delta(u)-X(3)Sigma(g)(-)) system. These bands had been previously attributed to the oxygen dimer, (O-2)(2). Under atmospheric conditions the Wulf bands are thus the long wavelength extension of the Herzberg continuum. Absorption of solar radiation by the Wulf bands may be an additional source of NO in the stratosphere. (C) 1998 Elsevier Science B.V. All rights reserved.
