Acoustic cavitation, the growth and rapid collapse of bubbles in a liquid irradiated with
ultrasound, is a unique source of energy for driving chemical reactions with sound, a
process known as sonochemistry. Another consequence of acoustic cavitation is the
emission of light [sonoluminescence (SL)]. Spectroscopic analyses of SL from single
bubbles as well as a cloud of bubbles have revealed line and band emission, as well as an
underlying continuum arising from a plasma. Application of spectrometric methods of …
