Both theoretieal and applied principles vere presented in sessions on emission, molecular and atomic absorption, x-ray, mass, nuclear, electron, and nuclear magnetic and electron spin resonanee spectroscopy; air and Water pOllution analyses; biomedical technology; polymers and elastomeric materials; and computer applications.
