Abstract :
Multibubble sonoluminescence spectra were recorded in the 300–350 nm wavelength range in the case of H2O/Ar, D2O/Ar and H2O/Kr solutions (acoustic frequency: 20 kHz; spectral resolution optimized to 0.34 nm). Three groups of rotational components (R1/R2, Q1/Q2 and P1/P2) were identified in the OH/D A2Σ+–X2Πi (0,0) transitions via the substitution of H2O for D2O. The congestion of bands and the origin of a red shading extending up to 350 nm are broached.
