摘要：

A new ultrasonic resonator method is described for measuring absorption in the frequency range 0. 1-1. 5 MHz in liquids. The method uses a plano-concave resonator with 56 mm diameter which shows high-Q characteristics enabling absorption measurements down to 0. 1 MHz to be carried out. A resonance spectrum is detected using Raman-Nath light diffraction instead of the quartz transducer. The results in water and benzene demonstrate the resolution of the apparatus. Absorption spectra of methyl and ethyl formate are presented.
