14N216O LINE BROADENING INDUCED BY AIR PRESSURE USING CRDS-SPECTROMETER IN THE 830 NM REGION

The measured and calculated broadening and shift coefficients of N2O lines by air pressure in the 830 nm region are presented at room temperature. Experimental data were obtained using CRDS spectrometer with an absorption sensitivity of 6.5×10-11 cm-1. The calculations were performed using the semiclassical method, modified by including a correction factor in the calculation scheme. The obtained coefficients of broadening and shift of N2O lines by air pressure are in good agreement with literature data.
