摘要：

The 3 nu(OH) and 4 nu(OH) of H2O, HNO3, and HO2NO2 have been observed. The band strengths of 3 nu(OH) are (7.0 +/- 1.8) x 10(-20) (2.9 +/- 0.7) x 10(-20), and (3.8 +/- 1.1) x 10(-20) cm(2) molecules(-1) cm(-1) for H2O2 HNO3, and HO2NO2 respectively. Those of 4 nu(OH) are (4.5 +/- 1.6) x 10(-21), (2.8 +/- 1.0) x 10(-21) and (3.0 +/- 1.8) x 10(-21) cm molecules(-1) cml for H2O2, HNO3, and HO2NO2, respectively, The uncertainty is for one standard deviation. Assuming excitation of these modes by solar absorption is dissociative for HO2NO2, these measurements confirm that this process will play a small role in the atmospheric photochemistry of the lower stratosphere.
