Intensity of the second and third OH overtones of H_2O_2, HNO_3, and HO_2NO_2
Chicago
Abstract
The 3ν_(OH) and 4ν_(OH) of H_2O_2, HNO_3, and HO_2NO_2 have been observed. The band strengths of 3ν_(OH) are (7.0±1.8) × 10^(−20), (2.9±0.7) × 10^(−20), and (3.8±1.1) × 10^(−20) cm^2 molecules^(−1) cm^(−1) for H_2O_2, HNO_3, and HO_2NO_2, respectively. Those of 4ν_(OH) are (4.5± .6) × 10^(−21), (2.8± .0) × 10^(−21), and (3.0±1.8) × 10^(−21) cm^2 molecules^(−1) cm^(−1) for H_2O_2, HNO_3, and HO_2NO_2, respectively. The uncertainty is for one standard deviation. Assuming excitation of these modes by solar absorption is dissociative for HO_2NO_2, these measurements confirm that this process will play a small role in the atmospheric photochemistry of the lower stratosphere.
