Первые исследования сверхтонкой квадрупольной вращательной структуры винилхлорида (C2H3 35Cl) в высоковозбужденных вращательных состояниях

Abstract

In the present study, the analysis of high-resolution rotational spectra of C2H3 35Cl was performed. The absorption spectra were registered in submillimeter-wave regions from 170 up to 1100 GHz in Universität zu Köln (Germany). About 5100 line positions for the values of quantum numbers up to Jmax = 93 and Kmax a = 27 were assigned to the ground vibrational state. The fit of the parameters of the Hamiltonian and of the quadrupole splitting χ−parameters was made. The obtained set of twenty three rotational and centrifugal distortion parameters and two χ−parameters reproduces quadrupole-rotational transitions with the drms = 20 kHz
