Abstract

Using a tunable diode laser spectrometer with a spectral resolution of about 10−4 cm−1, the important central portions of the two ir absorption bands of H2SO4 at 8.2 μm (1222 cm −1) and 11.3 μm (880 cm −1) have been scanned at low pressure (0.67 Torr of H2SO4) and atmospheric pressure (H2SO4 with ∼1 atm N2). Maximum absorption coefficients have been measured to be 6.5 cm−1-atm−1 and 6.9 cm−1-atm−1 at the 8.2-μm and 11.3-μm bands, respectively. A novel spectroscopic method was used to determine the temperature dependence of the dissociation of H2SO4 into SO3 and H2O in the 127–220°C range.
