摘要：
The high-resolution (0.05 cm(-1)) spectra of gas-phase H2SO4, HDSO4, and D2SO4 were measured over the frequency region 1200-10,000cm(-1) using Fourier-transform infrared spectroscopy. The increased resolution of this work compared with previous studies has lead to an improved vibrational analysis of H2SO4 . This study has answered unresolved questions about combination bands and overlapping features from previous gas-phase spectroscopic studies of H2SO4 and marks the first experimental measurement of the v(8) and v(15) torsional vibrations in this molecule. This work leads to a brief discussion on vibrational mode mixing in sulfuric acid. (C) 2004 Elsevier B.V. All rights reserved.
