The Multi-bubble sonoluminescence(MBSL) provides a unique environment, that is, very high temperature$(5,000\sim20,000K)$ and high pressure$(500\sim10,000\;atm)$. However, the mechanism for the MBSL has been elusive. Recently, it has been suggested that the mechanism be continuous and also of discrete peaks that are caused by molecular transitions. In this article, this mechanism has been examined for the Ar/water system by the combined hydrodynamics and molecular transition.
