Abstract: We describe the design, construction, and operation of a new type of microwave spectrograph which allows the measurement of the resonant transitions of transient or otherwise short‐lived species. The spectrograph is composed of three parts: a Fabry–Perot cavity, a pulsed supersonic nozzle as a source for the sample, and the pulsed microwave Fourier transform method. Following a detailed discussion of the three above components in the spectrograph, the operation of the entire system is described and several examples are given.

Fluorination effects on the shapes of complexes of water with ethers: a rotational study of trifluoroanisole-water.
TL;DR: The rotational spectra of five isotopologues of the 1:1 complex trifluoroanisole-water have been investigated with pulsed jet Fourier transform microwave spectroscopy, and the triple fluorination of the methyl group greatly affects the features of the rotational spectrum of the complex with water.

TL;DR: In this article, the microwave spectrum of the molecular complex of acetonitrile (CH 3 CN) with water (H 2 O) has been studied with a pulsed-beam Fourier Transform Microwave Spectrometer (FTMW) from a gas sample of 1% by volume of CH 3 CN in Ar flowed over a water sample.

Rotational spectrum and structure of the complex Ar–CH3CN
TL;DR: In this article, the microwave spectrum of the weakly bound complex Ar-CH3CN has been observed using a pulsed-nozzle Fourier transform microwave spectrometer, and the spectrum is characteristic of an asymmetric rotor with nearly free internal rotation of the methyl group.

Rotational spectrum of vinyl fluoride···ClF: Are the π-bonding or nonbonding electrons the most nucleophilic region of vinyl fluoride?
TL;DR: In this article, the ground-state rotational spectra of C2H3F···35ClF and C2h3F·37ClF have been observed with a pulsed-nozzle, Fourier-transform microwave spectrometer and the Cl nuclear quadrupole coupling tensor χαβ (α, β=a, b, c) was determined in each case.

TL;DR: Rotational transitions belonging to 2-iodobutane (sec-butyl-iodide, CH3CHICH2CH3) were measured over the frequency range 5.5-16.5 GHz via jet-pulsed Fourier transform microwave spectroscopy to determine rotational constants, centrifugal distortion constants, quadrupole coupling constants, and nuclear spin-rotation constants.
