Vacuum ultraviolet photoelectron spectroscopy of transient species

Abstract

The He(I) photoelectron spectrum of the FO(X 2Π i ) radical, produced from the rapid reaction has been recorded. Three bands were observed corresponding to ionization of FO(X 2Π) to the X 3Σ-, 1Δ and 1Σ+ states of FO-. Analysis of the vibrational structure in each band gave estimates of , r e and D e in the corresponding ionic state.
