Spectroscopic Studies of Multi -Bubble and Single Bubble Sonoluminescence

309 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2002.Single bubble sonoluminescence (SBSL) was also studied. Small concentrations of organic solutes suppress SBSL from water containing dissolved air, but only when the solvents are volatile and can enter the bubble interior. These results were interpreted in light of the dissociation hypothesis for SBSL in water. This interpretation in turn led to the development of rationale for choosing other solvents for SBSL, a phenomenon heretofore only observed in water. Several other liquids were found to support SBSL from both spatially stable and moving bubbles and, for the first time, molecular emission was detected in SBSL spectra.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
