DATAFILE: (Cs)2_LappHarris(1966)_700K_470-670nm.txt
NAME: caesium vapor molecule
FORMULA: (Cs)2
AUTHOR(YEAR): LappHarris(1966)
T: 700K
λ: 470-670nm
BIBLIOGRAPHY: M. Lapp and L.P. Harris, "Absorption cross sections of alkali-vapor molecules: I. Cs2 in the visible, II. K2 in the red", J. Quant. Spectrosc. Radiat. Transfer 6, 169-179 (1966); DOI: 10.1016/0022-4073(66)90035-5
COMMENTS: Absorption measurements using a tungsten-filament lamp as a light source and a grating monochromator with a slit width of 0.036 nm

The blue absorption system around 480 nm developed at about 573 K, the weaker system around 580 nm at about 633 K, and the strong complex system near 625 nm developed at about 503 K

The absorption spectrum depicted in Fig. 5 has been digitized
