Understanding the way ions behave in the gas phase is important for solving atmospheric, astrochemical and biological problems. In Chemical Science’s latest Mini review, Arthur Suits, at Wayne State University, Detroit, US, and colleagues illustrate how high-resolution ion and electron imaging techniques can be used to study photofragmentation and photoionisation dynamics in ions. Examples discussed include the use of cation photodissociation to explore the upper atmosphere of Titan, Saturn’s largest moon.
