摘要
A continuous two-dimensional jet expansion in combination with an infrared diode laser spectrometer has been used to record a new subband of the weakly bound complex Ar-CO in the 2168 cm(-1) region. Twenty-two transitions were assigned to a thus far unobserved K-a = 0 van der Waals state at 36.765 cm(-1) above the ground state. This is the highest van der Waals mode of Ar-CO reported so far. These high lying energy levels will provide a very sensitive test for future ab initio and semiempirical potential energy surfaces.
