Abstract
Thorndike's value of 560×1010 cycles per centimeter‐atmosphere for the total intensity of the 15‐micron carbon dioxide band is used to calculate the line intensities at one atmosphere and 300°K. Calculation of absorption results in good agreement with published absorption curves by Martin and Barker. Absorption for 203 millibars and 218°K is recalculated, correcting previous errors and using better approximations.
