| Résumé | The weakly bound van der Waals complex CH₄–CO has been observed spectroscopically for the first time in the infrared (C–O stretching, ≈2143 cm⁻¹) and millimeter wave (80–107 GHz) regions. The spectraanalyzed here resemble quite closely those of the rare gas–carbon monoxide complexes, like Ne–CO and Ar–CO, and they almost certainly arise from CH₄–CO complexes composed of CH₄ in the lowest j=0 rotational state of A symmetry. The effective ground state intermolecular separation is 3.994 Å. Predictions are given here for the K=0 and 1 pure rotational microwave transitions of CH₄–CO in the A state. The infrared spectrum shows numerous additional transitions which must be due to CH₄–CO composed of methane in the F and E symmetry states, but these have not yet been assigned. Future microwave measurements on these F and E states will aid further progress on the infrared spectrum. |
