Infrared spectra of weakly bound Rg-CS_2 (Rg = He, Ne, and Ar) clusters formed in a pulsed supersonic slit-jet expansion have been recorded by exciting the CS_2 ν_3 fundamental band (˜ 1535 Cm-1) using a tuneable diode laser. Spectra were well fitted to a conventional semi-rigid asymmetric rotor Hamiltonian. The He-CS_2 spectrum was assigned to an a-type band, while spectra of Ne-CS_2 and Ar-CS_2 were well described by b-type bands, indicating a/b axis switching in transition from the He-CS_2 complex to the Ne-CS_2 and Ar-CS_2 complexes. The results show that the complexes have vibrationally averged T-shaped structures. The determined structural parameters along with the observed vibrational shifts are R=3.81, 3.57 and 3.71 {Å}, θ = 80.0, 86.9 and 86.4° and Δν = 0.171, 0.181 and 0.067 Cm-1 for He-CS_2, Ne-CS_2 and Ar-CS_2, respectively. Here, R is the distance between the rare gas and the carbon atom, θ is the the angle between R and and the CS_2 axis and Δν is the vibrational shift with respect to the free CS_2 monomer.
