Abstract

The vibrational relaxation dynamics of the ground 1∑g+ electronic state of C3 has been studied following IR multiple photon dissociation of allene. Wavelength and time resolved spectra, using dye laser-induced fluorescence are used to characterize the vibratioanl levels and their corresponding rise and decay rates. Vibrational relaxation rates are reported for C3 (1∑+g, 100 or 110) in the presence of Ar, He, N2, O2 and C2H2, in addition to the reaction rate constant of C3 (1∑+g. 000) with C2H2 of (2.2 ± 0.20) × 10-14 cm3 molecule−1 s−1.
