abstract
Depending upon the circumstances, the phenomena which accompany or are the consequences of two-photon absorption may be quite varied. The effects which have been reported to date are luminescence, internal and external photoelectric generation, and initiation of chemical reactions. In this paper, we point out that generation of soundwaves may also be expected on a theoretical basis, and we present experimental results which we believe may have demonstrated this effect in liquids consisting of solutions of molecules such as benzanthracene and benzpyrene.
