Abstract
In this paper we present the results of Н2 16О absorption spectrum investigation recorded by a high resolution Fouriertransform spectrometer IFS-125M in the region 15500 – 16000 cm-1. Absorption path of 34.8 m and resolution of 0.03 см-1 were chosen to record the spectrum. White type multipass absorption cell with a basic length of 60 cm were used. Light-emitting diode (LED) was applied as a source of radiation. Signal-to-noise ratio is about 104, making it possible to measure parameters of lines with intensity up to 2*10-27 cm/molecule. Least-square-fitting algorithm was used to retrieve of the spectroscopic parameters from measured spectral data set. Spectral line positions and line intensities derived from the fitting were compared to data obtained in previous works.
