Equivalent widths and band intensities of CO(2).
Equivalent widths of the 2.7- and 4.3-microm CO(2) bands have been measured at high pressures up to 50 atm. These equivalent widths can be expressed by the empirical equation of the form W = cu(m)P(n)(e). The line-by-line calculations for the equivalent width showed that the empirical values of Winters et al., ["Line Shape in the Wing Beyond the Band Head of the 4.3 microm Band of CO(2)," J. Quant. Spectrosc. Radiat. Transfer 4, 527-537 (1964)] are also applicable to our high pressure experiments for the 4.3-microm CO(2) band. Using the curve-of growth method, the band intensities of the 5.2-,9.4-, and 10.4-microm CO(2) bands were estimated to be 0.0199 cm(-2) atm(-1) STP, 0.0340 cm(-2) atm(-1) STP and 0.0208 cm(-2) atm(-1) STP, respectively.
