Abstract:	Eleven absorption lines belonging to one of the Fermi-tetrad bands of CO₂, (3, 0⁰, 1)_III centered at 6231 cm⁻¹, have been recorded by a newly constructed near-infrared diode laser spectrometer. Precise line parameters, linestrength, and self-broadening parameters were determined from the observed spectra by analyzing the data using the Galatry profile function.

Keywords:	CO₂ Near infrared Line profile Pressure effect Line intensity Lorentz width
