Abstract
The absorption by the V(1) (1151.38/cm) and V(3) (1361.76/cm) bands of SO2 has been studied between 1050 and 1400/cm (9.5-7.1 micrometers). Spectral curves of transmittance have been scanned with approximately 1/cm resolution for more than 200 samples varying in temperature from about 296 K to 575 K and in pressure from 0.01 to 16 atm. The objective was to provide data on SO2 absorption and emission that are required to interpret data obtained in this spectral interval on the emission by smokestack exhausts containing SO2. An extensive table provides information from which the emission between 1050 and 1250/cm can be calculated for temperatures between 296 k and 650 K. Water vapor absorbs and emits so strongly in the region of the V(3) band of SO2 that this band is probably not useful for remote sensing of smokestacks. Therefore, the V(1) band was emphasized. The strengths of the two prominent bands in molecules are: V(1), 371 plus or minus 20 x 10 to the -20th; and V(3), 3020 plus or minus 200 x 10 to the -20th. (Author)
