Pressure effect on the microwave absorption of oxygen

Article

Summary

The frequency shift of microwave absorption of oxygen as a function of pressure is calculated by the adiabatic and semiadiabatic methods. The results obtained taking into account the London dispersion interaction, the exchange forces interaction and the quadrupole-quadrupole interaction are in good agreement with the experimental data.

Riassunto

Si calcola in maniera adiabatica e semiadiabatica lo spostamento in frequenza delle righe d’assorbimento dell’ossigeno a 60000 MHz in funzione della pressione. I risultati ottenuti tenendo conto dell’interazione di dispersione, di scambio e di quadrupolo-quadrupolo sono in buon accordo con i dati sperimentali.
