Abstract

Quality factors and resonant frequencies of a resonant spectrophone have been measured as a function of pressure and the results compared to theoretical predictions which took into account classical surface and volumetric losses and molecular relaxation. Buffer gases investigated included the five noble gases, H₂, N₂, O₂, CO₂, N₂O, and SF₆. Typically 95% of the cavity losses were accounted for theoretically. Frequency shifts due to relaxational dispersion, nonideal gas behavior, and classical boundary layer effects were observed; all behaved as predicted by theory.
