The design of a microwave spectrograph constructed for precise measurements of line widths is described. The effects of microwave power, frequency and amplitude of the source modulation, and klystron mode curvature on the apparent widths of the spect

The linewidths of some 25 inversion spectral lines of ammonia in the frequency region of 18–29 kMc/sec have been measured. Corrections due to various effects such as source modulation, cell‐length broadening, and Doppler shift were applied to the

A microwave spectrograph designed for measurements of linewidth is described. The width spectrograph consists of the same general major components as a spectrograph for frequency measurements, but differs considerably in the requirements of the compo

A Zeeman modulated microwave spectrometer, specifically designed for K band rotational studies of gaseous free radicals and transient molecular species and using a Fabry‐Perot type resonator as the absorption cell, is described. The theoretical sen

Microwave rotational absorption lines of the NF2 free radical have been observed with a highly sensitive K-band cavity spectrometer. The observed hyperfine splitting of these lines is consistent with a J type coupling scheme for the four different an

We report the development of a tunable sub-millimeter laser source, operating in the 100-1000 micrometer wavelength range, using Stark tuned atomic Rydberg states of potassium. The sub-millimeter laser action is generated by optically pumping Rydberg

1976 International Conference on Submillimeter Waves and Their Applications.
Very high sensitivity and spectrometric resolution have been obtained for gaseous paramagnetic molecules by using fixed-tuned submillimeter lasers and tunable magnetic fields [1-4]. This technique, commonly called laser magnetic resonance spectrometr
