| Résumé | Rotationally-resolved infrared spectra of N₂O–Ar and N₂O–Kr are studied in the region of the N₂O ν₁ vibration (≈2224 cm⁻¹) using a tunable Quantum Cascade laser source to probe a pulsed supersonic jet. The N₂O–Kr ν₁ fundamental band is re-analyzed, together with previous ν₃ band data, using a unified scheme to fit the (small) observed Kr isotope splittings. This scheme is then transferred to analyze the bending combination band of N₂O–Kr near 2257 cm⁻¹ where isotope effects are much larger due to stretch-bend interactions. As a result, N₂O–Kr intermolecular bend (33.29 cm⁻¹) and stretch (34.48 cm⁻¹) frequencies are directly determined for the first time. Weak spectra are detected for both N₂O–Ar and –Kr corresponding to the (ν₁, ν₂ˡ², ν₃) = (11¹0) ← (01¹0) hot band of N₂O. Their analysis yields the magnitude of the splitting of the N₂O ν₂ bending mode into in-plane and out-of-plane components. These splittings are found to be significantly smaller than those observed in the analogous CO₂-containing dimers. |
