摘要：

Collision-induced absorption (CIA) by CO2 is measured in the 1100-1600 cm(-1) range using a Fourier-transform spectrometer with a resolution of 0.5 cm(-1). The current measurements, which agree well with previous ones but are more precise, reveal pronounced structures on top of both unresolved Fermi doublet bands consisting of P-, Q-, and R-like branches. Assignment of e-branches at 1284.75 cm(-1) and 1387.75 cm(-1) to (CO2)(2) dimers seems highly probable. The nature of other peaks observed in CIA and Raman spectra of the CO2 Fermi doublet region is discussed, (C) 1999 Academic Press.
