Summary
In this work the paramagnetic resonance of the triphenylmethyl radical has been investigated. The hyperfine structure spectrum is deduced using the Slater-Pauling theory. The agreement with the existing experimental data is satisfactory. The usefulness of paramagnetic resonance measurements as an investigation method in valence theory is stressed.
Riassunto
In questo lavoro si studia la risonanza paramagnetica del radicale trifenilmetile. Lo spettro di struttura iperfine è dedotto usando la teoria di Slater-Pauling; l’accordo coi dati sperimentali esistenti è soddisfacente. Si mette in rilievo l’utilità delle misure di risonanza paramagnetica come metodo di indagine nella teoria della valenza.
