REPORTS OF AN EFFORT TO MEASURE THE CONCENTRATION OF ATOMIC FREE RADICALS IN A MOLECULAR MATRIX AT 4.2 DEGREES K,
Abstract
An attempt to measure the concentration of atomic free radicals frozen at liquid helium temperature is described. A magnetic susceptibility method making use of the apparent change of weight of the (paramagnetic) frozen sample in a magnetic field was investigated. The theory of the technique and the details of the balance constructed for measuring the force changes are presented. The difficulties encountered in putting the method into practice, and the reasons for its failure are discussed. Some suggestions for possible improvements are given. (Author)
