Balle, Terrill Joseph 2014-12-13T20:10:59Z 2014-12-13T20:10:59Z 10000-01-01 1980 1980 This thesis establishes the elementary theory of three well known spectroscopic techniques and then combines them to bring forth a new and highly successful method of microwave spectroscopy. After a short introduction to cavity spectrometers, the foundations of the theory of a Fabry-Perot cavity, of molecular polarization and of molecular beams is presented as it relates to this spectrometer. The block diagram is presented that shows how these techniques are incorporated into a working system. Certain design considerations relevant to the construction of this spectrometer are discussed. The results of observations on weakly bound molecular complexes are briefly considered, with references to the journal publications for complete explanations. The potential of this new method to this and other scientific pursuits is considered. A summary of advantages and disadvantages is discussed in conclusion. The last chapter concerns the theory of a Josephson Junction microwave detector mixer. Made available in DSpace on 2014-12-13T20:10:59Z (GMT).
