Using a tunable diode-laser spectrometer, we have measured the self-broadening coefficients and strengths of 26 absorption lines in the v(3) - v(1) band of (CO2)-C-12 and (CO2)-C-13 at room temperature. These lines, ranging from P(34) to R(40), are located around 960.9 and 913.4 cm(-1), respectively for the (CO2)-C-12 and (CO2)-C-13 molecules. The collisional widths and the intensities were obtained by fitting Voigt and Rautian and Sobel%26apos;man profiles to the measured shapes of the lines. From the individual line intensities and using a least-squares method, we have determined the vibrational band strength as well as the Herman-Wallis factors for the v(3) - v(1) band of (CO2)-C-12 and (CO2)-C-13.
