Abstract

Using a 101 m absorption path-length cell, Fourier transform spectra of H₂+CO₂ mixtures have been recorded at room temperature in the region around 2.4 µm. This enables to quantify the absorption induced, by collisions with CO₂, in the central part of the fundamental band of H₂. These measurements, which cover 39504400 cm⁻¹ range, validate previous fully independent computations.
