Experimental techniques are proposed for developing a model to estimate structural vibrations induced by internal acoustic pressure at low frequencies. In these methods, the acoustic field and the structure are treated as a coupled system with the acoustic loading effect taken into account. The response model between the internal pressure and the surface vibration is established by a modified modal test on the coupled system. Experiments are performed to investigate the surface vibrations of a closed steel cylindrical shell excited by a loudspeaker inside. The experimental results show that developed techniques provide accurate estimation for the acoustically induced vibrations. (C) 1995 Acoustical Society of America.

The photodissociation of CBrCl3 at 248 nm has been studied by translational spectroscopy. The primary dissociation process is shown to produce exclusively CCl3 and Br with an average translational energy of 20 kcal/mol. From the measured anisotropy parameter beta=-0.4+/-0.2, CBrCl3 undergoes a simple C-Br bond scission after ''citation via an E<--A1 transition polarized perpendicular to this bond. A secondary dissociation process from CCl3 by absorbing an additional photon is also observed at high laser powers.
