Measurements of pressure broadening and pressure shifting by nitrogen in the 4.3-μm band of 12C16O2

Abstract Lorentz broadening and pressure-induced line-shift coefficients of 34 individual lines of the v3 band of 12C16O2 have been determined using nitrogen as the buffer gas. The parameters were derived from 0.01 cm-1 resolution infrared absorption spectra recorded at room temperature using the McMath Fourier transform spectrometer and a nonlinear, least-squares fitting algorithm. The results obtained are compared with available values reported in the literature.
