Abstract
The absorption spectra of three near-infrared bands of (CO2)-C-12-O-16 assigned to 00051, 10051 and 10052 have been obtained by intracavity laser absorption spectroscopy with a Ti: sapphire laser. Different pro cedures have been used to obtain absolute measurement of the intensity of the rotational lines and then to deduce the band intensity. Compar ison with previous conflicting photoacoustic measurements is discussed . The values obtained could serve as secondary reference standards for other intensity measurements of weak absorptions in the near-infrared range.
