DIELECTRIC DISPERSION.
Abstract
Construction of the 50-75 kmc (0.4 to 0.6 cm) broadband microwave spectrometer is in progress. Employing a backward-wave oscillator (operating in the range between 50 to 63 kmc) as a power source, the system is frequency stabilized by injection phase-locking with a harmonic derived from a crystal phase-lock frequency-stabilized system operating between 26.5 and 40 kmc. In an attempt to remove one of the inherent limitations of the generally employed impact-approximation theories of line broadening in the microwave region, namely the assumption of a classical path for the colliding particles, a treatment based upon the formalism of scattering theory was applied to the problem of the perturbation of rotational transitions. Calculations of the frequency shift of rotational lines were made. Molecular quadrupole moments for simple molecules were calculated.
