Sonoluminescence from OH(C 2 Σ + ) and OH(A 2 Σ + ) Radicals in Water: Evidence for Plasma Formation during Multibubble Cavitation
Résumé
Bubble trouble: Multibubble sonoluminescence spectra in water under Kr and Xe present emission lines of OH(C2Σ+–A2Σ+). This band, never observed in flames, indicates plasma formation in the collapsing bubbles.
