A recent study of the vibrational-to-vibrational (V-V) energy transfer between highly-excited oxygen molecules and ozone combines laser-flash photolysis and chemical activation with detection by time-resolved LIF [ ]. Partial laser-flash photolysis at 532 mn of pure ozone in the Chappuis band produces translationally-... 

It was observed by de Saussure in 1814 that heat is evolved during the adsorption of gases on charcoal, and quantitative measurements were made by Favre (24) (1874), Chappuis (1888), and Dewar (25) (1904). 

Chappuis (1888) observed that many inert solids evolve heat when moistened with water. Thus ...

The Huggins bands are in the 300- to 360-nrn region, whereas the 440- to 850-nrn region represents the Chappuis bands. As seen in Figs. 4.7 and 4.8, both absorptions are much weaker than the Hartley bands.

The absorption in the ultraviolet and visible regions consists of the Hartley bands (2000 to 3200 A), the Huggins bands (3000 to 3600 A), and the Chappuis bands (4400 to 8500 A). The absorption coefficients of these bands arc given in Figs. VI I2 andVI 12b. Figure VI 12c shows the absorption coefficients in the vacuum ultraviolet region. 

Since the absorption spectra are diffuse over the entire spectral region, no assignments of transitions have been made from the analyses of the spectra. Hay and Goddard (449) have recently assigned the Hartley bands to a transition (origin at 3515 A) and the Chappuis bands to... 

Fig. VHI-8. Photodissociation coefficients J of ozone and NOj in sec-1 as a function of altitude for an overhead sun and x = 45", respectively. Above 50 km 03 dissociates predominantly into O( D) + Ojf A) by photolysis in the Hartley band. Below 50 km the photolysis in the Chappuis and Huggins bands becomes progressively more important, producing 0(3P), 02(Jf3I ), and Oj( A). The extent of Oj( A) production is uncertain below 50 km. From Nicolet (738) for 03 and Shimazaki and Whitten (872b) for N02, reprinted by permission of Reidel and the American Geophysical Union.

At wavelengths greater than 310 nm, the Huggins bands correspond to the limit of the O3 ultraviolet absorption, and in the visible region (410— 850 nm) the Chappuis bands play an important role leading to the 03 photodissociation in the lower part of the atmosphere, troposphere, and lower stratosphere. 

Because of absorption in the three spectral ranges covered by the Hartley, Huggins, and Chappuis bands, the rate of photodissociation of 03 is a frequency of 10 2 sec-1 in the mesosphere, and greater than 10-4 sec-1 in the stratosphere and troposphere.
