Sonoluminescence from OH(C2Σ+) and OH(A2Σ+) Radicals in Water: Evidence for Plasma Formation during Multibubble Cavitation
Written by Rachel Pflieger on October 18, 2010 – 5:00 am -Bubble trouble: Multibubble sonoluminescence spectra in water under Kr and Xe present emission lines of OH(C2Σ+–A2Σ+) (see graphic). This band, never observed in flames, indicates plasma formation in the collapsing bubbles.
