In very recent years inorganic free radicals have been intensively and pro ductively studied. Already they are proven or postulated intermediates in a variety of synthetic inorganic processes. The papers in this volume do not ex haust the subject of free inorganic radi cals, but they aim rather to give a status report on what is believed will be an ex tremely active field of future chemical investigation. One of the best known inorganic free radicals, N02, is discussed in detail, as is also one of the most re cently discovered, NF2. Thus, this book contains not only historical background material but also reports of recent re search of the utmost timeliness and significance. 175 pp.
