A sound reaction: The ultrasonically driven disproportionation of CO in water causes formation of hydrated polymer of carbon suboxide (C3O2)n (see picture) enriched with a heavy 13C isotope. This finding indicates the presence of vibrationally excited CO molecules with a non-equilibrium Treanor distribution inside the cavitating bubble.
