Cross Sections / Halogens+mixed halogens / Br4,(Br2)2 / WenNoyes(1972)_303K_220-290nm

DATAFILE: Br4,(Br2)2_WenNoyes(1972)_303K_220-290nm.txt
NAME: bromine dimer
FORMULA: Br4,(Br2)2
AUTHOR(YEAR): WenNoyes(1972)
T: 303K
λ: 220-290nm
BIBLIOGRAPHY: W.Y. Wen and R.M. Noyes, "Ultraviolet spectra of single and double molecules of gaseous bromine", J. Phys. Chem. 76, 1017-1018 (1972); DOI: 10.1021/j100651a012
COMMENTS: Deviation from the Beer-Lambert law has been interpreted in terms of the formation of double molecules of Br2

Absorption cross sections (converted from extinction coefficients), which have been assigned to Br4

Error limits are listed in the third column of the datafile
