English Abstract Selective excitation techniques have been applied to pulsed microwave Fourier transform spectroscopy. The frequency selectivity in excitation has been reached either by a long, weak pulse, or by a DANTE multi-pulse sequence. The corresponding excitation spectra calculated from a density matrix theory are in good agreement with the experimental results. The selective excitation techniques have been combined with double resonance sequences in order to simplify the recorded one-or two-dimensional spectra. Furthermore, selective excitation techniques have been applied to burn ‘holes’ into rotational transition lines broadened by an inhomogeneous Stark field.
