• P15 OH Emission and Bubble dynamics in SBSL(Poster Session)

抄録

The emission from the excitied state of OH radicals has been observed from water in single-bubble sonoluminescence (SBSL). We present the experimental results exploring the correlation of OH emission with bubble instability. This emission was observed at low acoustic pressures where the intensity of continuum emission is very small. We examined the dependence of the dissolved Ar pressure on the OH line spectra in SBSL. Using a high-speed shadowgraphy, we observed the bubble trajectory, indicating that the OH emission originates unstable bubble that repeats fragmentation and coalescence. It is suggested that the variation of OH spectra is caused by the lowering of bubble collapse temperature or the formation of ArOH exciplex.
