Stabilization Technique

The high resolution spectrum of the 2 υ9 band of HNO3 has been recorded by a tunable diode laser spectrometer with a newly developed frequency stabilization technique. The spectral data were digitally stored and processed by a dedicated micro-computer in order to improve the sensitivity and the precision of the measurements. In addition to the anomalies due to the Fermi resonance with the υ5 = 1 state, we have observed the line doubling caused by the internal rotation of the OH group.

The absorption spectra of carrier free 14C16O2 in the spectral range of 2290-2150 cm−1 by a medium resolution FTIR spectrometer, and the spectral region of 2258 − 2229 cm−1 with a high resolution tunable diode laser spectrometer have been recorded. Spectroscopic constants were calculated from the 0001 − 0000 and 0111 −0110 transitions.

Abstract By modifying the wavelength of the open path tunable diode laser spectrometer (TDLS) in the near infrared region, theoretical research was implemented to improve the detection limit of carbon monoxide gas. To adjust the correct wavelength in the NIR area, MatLab code was created. Following that, frequency domain measurements were performed in order to extract the second harmonic as an indicator of gas presence. According to the results, the correct wave length in the NIR area is (1584.877 nm), and the lowest limit of CO gas concentration is (0.012 ppb).
