In the past few years it has become apparent that Fourier Trans form infrared spectroscopy is developing into an excellent technique for solving some of the very difficult problems encountered in analytical chemistry. The applications of FT-IR include the detec tion and identification of chemical components separated by gas chromatography techniques, determination of low concentration com ponents in a mixture, and problems which have energy limitations such as water samples, opaque samples and biological systems. The lectures presented in this volume will be utilized at the NATO Advanced...

Our knowledge of the distribution and properties of the small solid particles within the solar system continues to improve rapidly. Much of the progress is due to observations from spacecraft which offer completely new locations from which to view phenomena such as the zodiacal light. In combination with ground-based observations and improved theoretical models, a picture now emerges with a clarity un- attainable even a few years ago. The need for a survey of the situation was recognized in 1976 and, at meetings of COSPAR and the International Astronomical Union in that year, planning began...
