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.
