Bahou, C.-Y. Chung, Y.-P. Lee, B.-M. Cheng, Y.L. Yung, L.C. Lee Title: Absorption cross sections for HCl and DCl at 135-232 nm: implications for photodissociation on Venus Journal/Source: Astrophys. J. Lett., 559 (2), L179-L182, (2001); doi: 10.1086/323753 Data: diagram, table Energy/Wavelength range: 135 - 230 nm Resolution: 0.1 nm; 2.5 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: pH: Comments: Cross sections for photoabsorption of HCl and DCl are determined in the spectral region of 135-232 nm using radiation from a synchrotron light source. At wavelengths near the onset of absorption (lambda > 200 nm), cross sections of HCl are approximately 5-10 times larger than those of DCl.
