Abstract

In the spectral range 34500-40000 cm-1, two molecular species were detected by means of laser-induced fluorescence in the 193 nm photolysis of acetylene: one is C2(a 3Πu), the other is most likely C2H(X). The identification of C2H is based u the rotational constants (B″ = 1.4397-1.4534 cm-1), the deuterium isotope effect on the vibronic bands, and the wavelength-resolved fluorescence.
