     An Atomic Force Microscope (AFM) has been used to measure photothermal 
     displacement of a surface, thus acting as a local photoacoustic 
     detector.  This was demonstrated with filter and Fourier Transform 
     Infrared (FTIR) spectrometers on polymer samples.  Similarly, surface 
     fractions were removed by an AFM tip and analyzed by the photothermal 
     deformation of the coated cantilever.  This work shows that the AFM 
     can function both as a precise surface separation device and a 
     detector for spectroscopic analysis.  The use of AFM photoacoustic 
     detection has the potential to enhance the sensitivity, selectivity 
     and spatial resolution of optical spectroscopy.
