Calculation of the Absorption Cross Sections of Some Molecules from GEISA Database at the Wavelengths of Isotopically Different CO2 Lasers

Table 4

For each CO2 laser and for each molecule M, the laser transitions with the largest absorption by selected molecules are presented. The cross sections (M) (in 10−20 cm2 units) and and coefficients are shown.
