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 H_2SO_4 at 8.2 μm (1222 cm ^−1) and 11.3 μm (880 cm ^−1) have been scanned at low pressure (0.67 Torr of H_2SO_4) and atmospheric pressure (H_2SO_4 with ∼1 atm N_2). 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 H_2SO_4 into SO_3 and H_2O in the 127–220°C range. |
