Summary
The statistical operator has been calculated for a gas with rotational levels, in the presence of two electromagnetic waves with frequencies in the neighbourhood of two contiguous resonances. The absorption coefficient has been determined for the two waves. The agreement with experiment is good.
Riassunto
Si è calcolato l’operatore statistico per un gas con livelli rotazionali, in presenza di due campi elettromagnetici di frequenze vicine a quelle di due risonanze contigue. Si è determinato il coefficiente di assorbimento per le due onde. L’accordo con l’esperienza è buono.
