Comments: Absorption coefficient data are presented for molecular oxygen at temperatures between 1100 and 2000 K and discrete 
wavelengths between 211 and 235 nm. Using the Beer - Lambert relation, the oxygen absorption coefficient beta was determined to 
be 0.021 (atm-1 cm-1) at 1307K and 211 nm, or sigma = 3.8 x 10-21 (cm2).
