The vibration-rotation of H₂O and its complexation with CO₂ in solid argon revisited
Fourier-transform infrared spectroscopy in the frequency range 400–4000 cm–¹ has been used to investigate the absorption of H₂O and H₂O:CO₂ complex isolated in solid argon. Thanks to the lowest temperature reached in our experiment, temperature effects and nuclear spin conversion studies allow us to...

An additional wide structure observed in this band shows two maxima around 1657.4 and 1661.3 cm–¹, with nuclear spin conversion of the high frequency part into the low frequency one.
