摘要
The self-broadened and nitrogen-broadened absorption profiles of the Q-branch head of the 1000 ← 0110 band of CO2 near 618 cm-1 were studied under high resolution (∼10-4 cm-1) using tunable diode laser techniques. The intensity and linewidth of several lines in this Q branch, the ν2 band, 10.4-μm and 9.4-μm laser bands have been measured accurately. The lineshape of a CO2 line has also been measured to be Lorentzian within experimental accuracy to about 15 half-widths. Preliminary calculated Q-branch head absorption profiles agree reasonably well with the observed profiles. © 1979.
