A graphical method for determining the width of microwave rotational lines of gases

  • Published:
Il Nuovo Cimento B (1965-1970)

Summary

A simple graphical method is developed for determining the width of lines of rotational spectra in the microwave region, for the limiting cases of high temperatures and low pressures. The method is discussed in detail for linear molecules and dipole-dipole force. As an application we have studied the limitations involved in the simplifying assumptions usually adopted for the internal and translational states of colliding molecules.

Riassunto

Si sviluppa un metodo grafico di calcolo per determinare la larghezza di riga degli spettri rotazionali nella zona delle microonde, per il caso limite di alte temperature e basse pressioni. Il metodo è discusso in dettaglio per il caso di molecole lineari e interazione dipolo-dipolo. Come applicazione si studiano i limiti delle ipotesi semplificative solitamente adottate riguardo agli stati interni e traslazionali delle molecole che collidono.
