Abstract
Photoabsorption and fluorescence cross sections of CS2 have been measured in the 1060-1520 AA region using synchrotron radiation. In the 1060-1200 AA region the absorption is smooth and continuous, except that a strong absorption band ( sigma a=2.1*10-16 cm2) shows at 1117 AA. For wavelengths longer than 1200 AA, the absorption spectrum shows the structure of Rydberg states. The fluorescence in the 1900-3000 AA region starts to appear at 1335 AA. This fluorescence is mainly the CS(A1 Pi to X1 Sigma +) transition in the 2400-2800 AA region. The fluorescence in the 1900-8000 AA region starts to appear at 1490 AA. In addition to the CS(A1 Pi to X1 Sigma +) system, the fluorescence is probably composed of the transitions of S(1S0 to 3P1) at 4589AA and of CS(d3 Delta , a'3 Sigma +, and a 3 Pi to X1 Sigma +) at 3000-4000 AA. The quantum yields for the production of fluorescence have maxima of 13 and 7.5% at 1235 AA for the fluorescence in the 1900-8000 and 1900-3000 AA regions, respectively.
