Abstract

A new band at 23 390 cm-1 in the Ã1Π u-X̃1Σg+ electronic transition of C3 has been recorded by laser-induced fluorescence at high resolution and rotationally analyzed. Based on the agreement of the lower state constants with infra-red data given by Kawaguchi et al. [9], the vibrational assignment is found to be 0 1 1(Δu)-0 1 1 (Πg). Seventeen of the 19 vibronic levels of the Ã1Πu state expected to lie below 25 700 cm-1 (a vibrational energy of 1025 cm -1) have now been identified.
