Abstract:

The infrared absorption spectra in the range 4000 to 400cm of the vapors above liquid H2SO4, 11 H2-SO4 D2SO4, and D2SO4 were measured and assigned to the respective gaseous molecules as well as equilibrium concentrations of SO3. SO2 was observed as a decomposition product. Assignment of the frequencies to the normal modes was made using correlations with the related near-tetrahedral molecules X-SO2-Y and with spectra of the condensed phases. Some frequencies are predicted for H2CrO4 and for unassociated gaseous chlorosulfonic acid. Author
