Infrared spectra of H2SO4 vapors, which also include H2O and SO3, were
trapped in argon matrices. Vibrational assignments for monomeric H2SO
4 were established and additional bands were assigned to the (H2SO4)(2
), (H2O).(H2SO4) and (H2O)(2) .(H2SO4) species. For the (H2O).(H2SO4)
complex, several isomers are shown to exist, the most stable being H2O
. HOSO2OH. Temperature reversible changes in several bands of the lat
ter complex are discussed in analogy to the trimeric (H2O)(3) complex.
The H2O and H2SO4 molecules dispersed in the argon solid do not affec
t the stabilization of a mixed (H2O)(m) .(SO3)(n) complex. No spectral
evidence for ionized species due to proton transfer was found in the
matrix samples investigated.
