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(Δ_u)-0 1 1 (Π_g). Seventeen of the 19 vibronic levels of the Ã¹Π_u state expected to lie below 25 700 cm^-1 (a vibrational energy of 1025 cm ^-1) have now been identified.
