Description

A general outline is given from the relaxation mechanisms governing the energy transfer between molecules in a vibrational state. The optical-acoustic method is discussed in which molecules are excited in a vibrational state by a pulsed infrared beam, causing sound waves. The amplitude as well as the phase shifts of these sound waves with respect to the optical pulses give information about relaxation times and also about the mechanisms involved
