Ionization potentials (IP's) of small carbon clusters (Cn, n=3-6) have been bracketed with an uncertainty of a few tenths of an eV by charge-transfer methods in a Fourier transform ion cyclotron resonance mass spectrometer. Values obtained are compared to previously determined experimental and theoretical values. Several interesting reactions other than charge-transfer were observed between the carbon cluster ions and the charge-transfer reference compounds. The products of these reactions are reported and discussed. © 1993 American Institute of Physics.
