Abstract
The paper describes the application and limitations of magnetic methods to the problems of free-radical chemistry (detection and quantitative investigation of the free-radical state, relationships between structure and free-radical formation, “distribution” of the unpaired electron, detection of mesomeric C, O, N, P, As, and Sn radicals, g-factors, triplet states, and hyperfine structure). The problem of the diradical is described, and the paper closes with a discussion of the “Selwood effect”.

The correct value, however, is −340. Thus the difference from the value on irradiation (−280) is only +60, i.e. equivalent to a diradical content of 1 to 2%; this value is within the limits of error, cf. [19].

Our measurements [89] showed the presence of a diamagnetic low-temperature form (↑ ↓) and a paramagnetic high-temperature form (↑↑) (ΔW ≈ 0.5 kcal/mole).
