Gas-phase spectra of four isotopic species of GaBr have been detected in the millimeter waveieugth region. The molecules were produced by a flame reaction of gailium and bromine at 1000Β°C. From the rotational spectra molecular constants have been determined for 6gGa7gBr, 6gGa81Br, 'lGa"Br, 7X Ga\*r

β¦ Synopsis
The millimeter wave rotational spectrum of gallium monofluoride (GaP) has been studied in the 250-300 GI-Ix frequency region. Using a new method of molecular production in a free space cell three rotational transitions of 6gGaP and four rotational transitions of 'iGaP in the u= 0, 1 and 2 vibrational states have been measured. The analysis including previous measurements on the lower rotational transitions in the microwave region yielded an improved and extended set of Dunham molecular parameters.
