An unusual application of PE spectroscopy is the optimization of gas‐phase reactions. Photoelectron spectrometers provide “fingerprints” of molecules in the form of ionization band patterns. Gas‐phase formation of ketene by elimination of HCl from acetyl chloride serves as an example. Information about the reaction mechanism can be obtained, e.g. from the PE spectrum of the residual gas(CO,CH 4 ) which does not condense at −190°C.
