... In a first part we describe recent spectroscopic results related to the UV-visible emission from alkali metal - rare gas (M-Rg) and OH(D)-Rg excimers in aqueous and organic multibubble sonoluminescence (MBSL). Three points are analysed: (a) the detection of excimers in MBSL emphazises a singular property of bubbles, namely to break strong molecular bonds (e.g., D0 H-OH = 498 kJmol-1) and to generate fragile van der Waals (vdW) species (D0 Ar-OH* = 8.8 kJmol-1). ...
