| Abstract | The infrared spectrum of CO₂-Kr complex is studied in the region of the carbon dioxide ν₃ fundamental vibration (≈2350 cm⁻¹). Tunable IR radiation from an OPO is employed to record absorption spectrum of the complex generated in a pulsed supersonic slit jet. The spectrum exhibits broadening and splitting of transitions due to mass dependence of the five Kr isotopes with natural abundances exceeding 2 %. Good simulation of the spectrum is achieved by scaling the vibrational and rotational parameters. This scaling model is particularly important for the combination band involving the intermolecular bending mode where many isotope splittings are observed. As with other CO₂-rare gas complexes, we also observe weak hot bands of CO₂-Kr transitions corresponding to the hot band originating in the CO₂ intramolecular bend. From these we determine a splitting of 1.418 cm⁻¹ between the in-plane and out-of-plane bend of CO₂, due to the neighboring Kr atom. |
