Oscillations in a laser-induced chemical reaction: coupling of chemical reactions with an acoustic effect

An oscillatory phenomenon has been observed in a laser-induced photochemical reaction occurring in a degassed acetone or benzene solution of the complex [}Au[P(C6H4OMe-p)3{]2-(μ-CC)] after flash photolysis. It been confirmed that the observed oscillation is due to the chemical reactions coupling with the photoacoustic effect.
