Summary
By the method of mechanical detection previously described multiple quantum transition involving both σ and π photons have been observed in the paramagnetic resonance of DPPH. The intensities and shifts of the various resonances have been studied as a function of the intensity of the applied r.f. fields and compared to the theoretical results.
Riassunto
Utilizzando il metodo della rivelazione meccanica, descritto in precedenza (4,5), transizioni a più quanti con fotoni σ e π sono osservate nella risonanza paramagnetica del DPPH. L’intensità e gli spostamenti delle righe di risonanza sono studiati in funzione dell’intensità dei campi a radiofrequenza applicati, e sono paragonati ai risultati teorici.
Реэюме
В параметрическом реэонансе DРРН, испольэуя метод механического детектирования, предварительно описанный в (4,5), наблюдались многоквантовые переходы, включаюшие и σ и π фотоны. Были иэучены инетенсивности и сдвиги раэличных реэонансов, как функции интенсивностей приложенных r.f. полей, и проведено сравнение с теоретическими реэультатами.
