S. Baldelli et al., FIRST SPECTROSCOPIC EVIDENCE FOR MOLECULAR HCL ON A LIQUID SURFACE WITH SUM-FREQUENCY GENERATION, The Journal of chemical physics, 108(23), 1998, pp. 9817-9820
Sum frequency generation spectroscopy has been used to obtain the vibr
ational spectrum of HCl on the surface of a liquid. HCl was studied on
the surface of 96 wt % H2SO4, 12 M HCl solution, liquid HCl and glass
, of which only liquid HCl produces a resonant signal. Implications fo
r the form of HCl on surfaces and the reactions in the atmosphere are
discussed. (C) 1998 American Institute of Physics.
