✦ Synopsis

Metastable evaporation of carbon cluster ions produced from excimer laser ablation of polyimide has been investigated in a reflectron time-of-flight (TOF) mass spectrometer. Rate constants for the decay process are extracted from the parent and fragment peak intensities. The rate constants increase with decreasing delay between laser pulse and TOF extraction field for a given laser fluence and decrease with increasing laser fluence for a given delay.

The electronic energies and geometries of the 'A, ring and the 'C.$ linear isomers of C,, have been computed and compared at the HF, MP2 and DFT levels. Previous DFT calculations predicted the ring to be more stable than the linear form by about 20-30 kcal/mol, which is in apparent conflict with a r
