Abstract : The laboratory in which the experimental aspects of the Molecular Structures program will be carried out has been designed and constructed. The majority of the main instrumentation to be employed has been assembled and installed. Some of this equipment is described in detail. Two aspects of the program to study the interaction of radiation with matter are described in some detail. The first study involves the interaction of ice with high energy gamma-rays, and a theoretical model is described which predicts the buildup curve of stabilized hydroxyl radicals at 77K. The second part of the program involves the role of the triplet state in intermolecular energy transfer. Some preliminary results are reported which illustrate the technique of using EPR (Electron Paramagnetic Resonance) techniques to observe triplet states at low temperatures. (Author)
