Abstract:

The methane spectrum is studied near R(3) and R(4) multiplets of the first vibrational overtone in the 298–720 K temperature range with a tuning diode laser. We have developed the technique for laser radiation measurement and frequency calibration with the use of a high-stability plain-mirror interferometer. The coefficients of collisional broadening by nitrogen are calculated at different temperatures.

Keywords:

methane spectrum, collisional broadening, diode laser, Fabry–Perot interferometer
