Abstract

The dispersed fluorescence (DF) spectra of the C$_3$Ne, C$_3$Ar, C$_3$Kr, and C$_3$Xe complexes near the 0 2$^-$ 0- 000, 0 4$^-$ 0- 000, 0 2$^+$ 0- 000 and 100-000 bands of the ~{A}-~{X} system of C$_3$footnote{G. Zhang, B.-G. Lin, S.-M. Wen, and Y.-C. Hsu, J. Chem. Phys. {bf120}, 3189(2004); J.-M. Chao, K. S. Tham, G. Zhang, A. J. Merer, Y.-C. Hsu, and W.-P. Hu, J. Chem. Phys. {bf134}, 074313(2011)} have been revisited. Some of the DF spectra of the Ne and Ar complexes have been recently obtained with a slightly improved resolution of 6-10 wn. All the DF spectra have been reassigned as emission from van der Waals (vdW) complexes and C$_3$ fragments. The optically excited C$_3$-Rg (Rg = rare-gas atom) complexes fluorescence and/or decay down to slightly lower (about 2-30 wn) vibrational levels without changing the internal energy of C$_3$ and then predissociate via the continua of the nearby vibronic states of C$_3$. The available dissociation channels depend on the binding energy of the ground electronic state complex. Exceptions have been found at the vdW bands near the 0 4$^-$ 0- 000 band of C$_3$. The binding energies of the ground electronic states of these four complexes will be discussed.
