| Abstract: | An improved pulsed microwave spectrometer for the detection of rotational transitions in gaseous molecules in the frequency range of 130–150 GHz is described. It incorporates a tunable Fabry-Perot cavity and a low noise superneterodyne receiver for the detection of the molecular emission signals. The molecules are excited by π/2 pulses provided by a high efficiency frequency doubler which is pulse modulated at an IF frequency of 1.4 GHz. |
