Abstract : A summary is given of experimental and theoretical accomplishments in the following areas: development of double resonance microwave techniques and their application to the testing of quantum number assignments and of relaxation phenomena in gaseous systems; design and application of a modulation type spectrometer which does not utilize the Stark effect; analysis of microwave spectra of molecules having internal rotation and extracting therefrom the barrier to internal rotation; microwave spectroscopy of 63 chemical species, with particular attention given to molecular structure and the effects of vibrational motion; quantum mechanical calculations of energy levels, especially with respect to error bounds to expectation values and to the utilization density matrix methods. A list of the 111 papers generated as a result of the work is included.
