摘要：

Absorption coefficients of the carbon dioxide (CO2) were measured at atmospheric pressure and room temperature by photoacoustic technique with a cw, line-tunable, frequency stabilized CO2 laser. The CO2 laser spectrum of our system consists in 53 lines with wavelengths ranging from 9.2 mu m to 10.8 mu m and power levels below 5 W. Measured values of the CO2 absorption coefficients are typically of 10(-3) atm(-1)cm(-1) order of magnitude, with the highest absorption coefficient of 3.01x10(-3) atm(-1)cm(-1) observed at 9P(18) laser transition. Compared with other values reported in the literature, the obtained results revealed a good agreement.
