Startling facts are often revealed by the quantitative investigation of a reaction thought to be understood. The photoionization of dimethylaminobenzonitrile, which was previously regarded as biphotonic, was found to occur by the successive absorption of three photons, and to produce two electrons per starting molecule [Eq. (1)]. The explanation is an intervening rapid chemical reaction: deprotonation followed by intramolecular charge transfer.
