Trapping of Free Radicals at Low Temperature

, Describes the behavior of free radicals and explains the theories related to their activities. Shows an experiment in the trapping and storing of free radicals at temperatures near absolute zero through a special technique developed at the National Bureau of Standards. Pictures the handling of liquid helium and displays the brilliant colors in glows and flashes that emanate from the free radicals trapped in a solid matrix of frozen gas. Relates that when trapped in this matrix they remain long enough to be studied by spectroscopy and electron spin resonance., Describes the behavior of free radicals and explains the theories related to their activities.
