Emission bands of the C3-Xe van der Waals complex near the 22-0, 22+0, and 24-0 bands of the Ã-X system of C3 have been recorded, but as yet definitive spectral assignments could not be made. Unlike those of the C3-Ar and C3-Kr complexes, the observed C3-bending vibrational progressions of the Xe-complex could not be fitted to a simple dipole-induced dipole model potential. Ab initio calculations of the Ar- and Xe-complexes have been carried out using the CCSD(T) method at the cc-pVQZ level. Tentative vibrational assignments of the Xe-complex based upon the ab initio calculation will be discussed.
