We discuss the role of isolated radicals in various chemical environments, like combustion engines, low-temperature plasmas, planetary atmospheres and interstellar space. Several methods to generate radicals are presented, e.g. pyrolysis, photolysis, discharges, chemical reactions and neutralization-reionization mass spectrometry. The breadth of each method is illustrated and species generated by these methods are introduced. It is shown that photoionization is an important tool to detect radicals and unravel their reactions. However, the often small Franck-Condon-factors have to be considered when interpreting photoionization data. Selected results on the unimolecular and bimolecular reactions of radicals are discussed with the intention to show the scope of present methods to study radical chemistry in the gas phase. Among these methods are time-resolved laser spectroscopy, mass spectrometric techniques like charge-tagging and schemes based on detecting radicals with synchrotron radiation.
