Abstract
A diode laser spectrometer, which is ment for recording ortho-and paracomposition of water vapor in gas mixtures, is described. The studied mixture is probed by infrared radiation at frequencies of the resonance absorptions of ortho-and paramolecules of water (λ ≈ 1.85 μ m). The recording rate of spectral ortho-and paralines is 2 Hz, and the ortho/para composition is calculated in real time with respect to their integrated intensities. An accuracy of 1% is ensured in a 0.01- to 20-Torr partial pressure range for water vapor and in a 0- to 700-Torr partial pressure range for the buffer gas.
