CRDS absorption spectra used in the paper entitled: "Temperature dependence of the collision-induced absorption band of O2 near 1.27 µm"

The data set corresponds to absorption spectra of pure O₂ and air recorded with a cavity ring down spectrometer at 332 K and 271 K for different total pressures of the gas.

Each file corresponds to one spectrum and contains four columns: wavenumber (in cm-1); absorption coefficient (in 10^-6 cm^-1); total gas pressure (in Torr); gas temperature (in °C). For all the spectra, the base line, determined from argon spectra recorded in the same conditions of pressure and temperature, has been subtracted.  

The file name of each file is composed as follows: Spec_Gas_Pressure_Tset_Laser source.txt.  

Note that for the spectra obtained with an ECDL light source, only the first two columns are available.
