A number of 1720-MHz OH maser sources have relatively simple spectra consisting of doublets with opposite senses of circular polarization. Such doublets could be due to the Zeeman splitting of the $sup 2$Pi$sub 3$/$sub 2$ F=2$Yields$1 transition. A three-station VLBU experiment was conducted to measure the spatial separation of the emitting regions of the components of opposite sense polarization. The doublets in the 1720-MHz OH spectra of W3(OH), W51, NGC 6334 (N), and NGC 7538 (N) are found… CONTINUE READING
