A number of reasons for the appearance of anomalous intensities in zero-kinetic-energy (ZEKE) spectroscopy are briefly reviewed and extended. Particular attention is paid to a recent paper of Matsui, Behm, and Grant in which the authors detect, in the ZEKE spectrum of NO2, a number of Franck-Condon forbidden transitions of significant intensity which they attribute in large part to channel interaction between allowed continua and Franck-Condon forbidden discrete Rydberg series. A quantitative approximate analysis of their data is given here which supports this claim. Implications of these results for final state interactions in photoelectron spectroscopy are discussed.
