Abstract
A simple method for absorption coefficient measurement of liquids in t he range 0.1-10(4) cm(-1) is demonstrated and a few spectroscopic appl ications in this whole range are presented. The detection scheme uses an open photoacoustic cell with piezoelectric transducer and laser exc itation of a thin (0.5-700 mu m) sample layer.
