520 $a The role of vibrations in the atmosphere has been explored in two cases.
520 $a A new mechanism for OH production in the mesosphere is assessed. Vibrationally excited H2, formed by the collisional energy transfer from <math> <f> <rm>O<inf>2</inf><fen lp="par"><g>S</g>+<inf><mit> g</mit></inf>1<rp post="par"></fen></rm> </f> </math>, reacts with O(<super>3</super>P) to yield OH. This contributes 16% to the total OH production at 100 km altitude.
520 $a Overtone-induced chemistry of trifluoroacetic acid is considered. The elimination of HF is the lowest energy dissociation pathway [50.3 kcal mol<super> −1</super> (MP2/6-311G(2d,p))]. The second fragment forms a stable fluorinated epoxide, CF2CO2. The absorption cross sections of the <italic> v</italic>OH = 3, 4, 5 overtones are (2.70 ± 0.09) × 10<super>−20</super>, (1.68 ± 0.19) × 10<super>−21 </super>, and &sim;1.5 × 10<super>−22</super> cm<super>2</super> molec<super>−1</super> cm<super>−1</super>, respectively. Excitation to the <italic>v</italic>OH = 5 or 6 leads to dissociation; the rate constants are 3.7 × 10<super>−9</super> and 2.5 × 10<super> −10</super> s<super>−1</super>, respectively. The overtone-driven photodissociation is more important than the ultraviolet photodissociation in the troposphere, but is insignificant in comparison to wet deposition and reaction with OH.
