摘要：

Diode laser measurements of CO2 absorption spectra have been made in the 2270-2295 cm-1 spectral region at low pressure (&25 mbar) and at temperatures up to 800 K. Line intensities of several parallel hot bands (20013 ← 20003, 12212 ← 12202, 20012 ← 20002, 12211 ← 12201, 20011 ← 20001, and 01121 ← 01111 bands of 12C16O2, and 01111 ← 01101 band of 13C16O2) have been obtained. The data are analyzed to derive squared dipole-moment matrix elements and band intensities. Our results for the 01111 ← 01101 band of 13C16O2 are consistent with previous measurements performed at room temperature. The values obtained for the 12C16O2 bands investigated in this work, which to our knowledge have not been analyzed previously, are in good agreement with available theoretical predictions. © 1993 Academic Press, Inc.
