Abstract

The pure rotational lines of H(2)O, the nu(2) band of CO(2), and the nu(1) band of OCS were simultaneously recorded by a Fourier transform spectrometer. The resolution achieved was ~0.0045 cm(-1), and the precision of the line position was typically 3.6 x 10(-5) cm(-1) or 1.2 MHz (standard deviation). The spectrum improves the accuracy of wave numbers of calibration lines in the region between 500 and 720 cm(-1) by a factor of ~10.
