We report that in spite of the commonly accepted view that stable Single-Bubble Sonoluminescence (SBSL) can only be achieved in water in the presence of a noble gas or hydrogen, long term stable SBSL can in fact be sustained with only diatomic gases like e.g. nitrogen being present. Compared to that of a stable argon bubble, the emission is much weaker and the spectrum looks much colder. Simulations support that the above quoted view, based on the dissociation hypothesis, is an erroneous inference from this theory.
