โœฆ Synopsis

Two-dimensional (2D) correlation techniques were applied to microwave Fourier transform (MWFT) spectroscopy. A threepulse sequence supplied with a phase cycle acting as a double-quantum filter as well as a two-pulse "CO%" sequence were found to be useful for the correlation of connectivities between rotational transitions. Experiments were performed on l-chloro-l-fluoroethene in order to show common energy levels within the 35C1 hypertine structure. The relationship to similar NMR techniques is also discussed.

"Pure" quadrupole transitions have been observed in \(\mathrm{CF}_{3}{ }^{79} \mathrm{Br}\) and \(\mathrm{CF}_{3}{ }^{81} \mathrm{Br}\) using the technique of two-dimensional Fourier transform spectroscopy in the microwave and radiofrequency range. We observed transitions for \(J=4,5,6\) and \(K=1,
