Davidovits, D.C. Brodhead Title: Ultraviolet Absorption Cross Sections for the Alkali Halide Vapors Journal/Source: J. Chem. Phys., 46, 2968-2973, (1967); doi: 10.1063/1.1841164 Data: table, diagram Energy/Wavelength range: ~ 200 - 390 nm Resolution: Temperature: 1020 - 1120 K Temperature dependence: yes Pressure/Concentration: Phase: vapor pH Comments: The ultraviolet absorption cross sections for the alkali halide vapors were measured in the region from 2000 to 4000 Å. The absorption cross section of the first peak in the spectrum is (2.2 + 0.0 - 0.3) x 10-17; the second (3.9 + 0.0 - 0.5) x 10-17 and the third (7.4 + 0.0 - 1.2) x 10-17.
