Paper Abstract

Precise molecular spectra obtained by Tunable Diode Laser Spectrometers were fitted by Voigt profile using routine development. All line parameters (transition frequencies, line intensities, Lorentzian and Gaussian parameters) were obtained from this fitting. Different effects limiting TDLS precision such as laser noises, detector non-ideality, zero absorption and zero transmission levels determination, etc., were considered. Results are presented in analytical form showing error dependence upon various experimental parameters. The results were tested through computer modeling and compared with the obtained experimental results. Some procedures were proposed to minimize the influence of main error sources.
