Sonoluminescence from Nonaqueous Liquids: Emission from Small Molecules

Research output: Contribution to journal › Article › peer-review

Abstract

Sonoluminescence spectra from nonaqueous liquids under a variety of gases are presented. Ultrasonic irradiation of alkanes under Ar leads to emission from C₂, C₂H, and CH. When nitrogen is present, emission is seen from CN. When oxygen is present, emission from CO₂, CH, and OH is observed. Ultrasonic irradiation of tetrachloroethylene or CC1₄ leads to emission from Cl₂. The intensity of sonoluminescence decreases as the liquid vapor pressure increases. The properties of the dissolved gas also influence the sonoluminescence observed. Sonoluminescence is caused by chemical reactions of high energy species formed during cavitational collapse. It is a form of chemiluminescence. The principal source of sonoluminescence is not blackbody radiation or electrical discharge.
