Abstract

At wavelengths near 1 mm six rotational transitions of GaCl have been observed. The analysis including previous measurements on the rotational transitionJ = 1 ← 0 resulted in extended sets of the Dunham parametersY 01,Y 11,Y 21,Y 31,Y 02,Y 12 andY 03 of the four isotopic species69Ga35Cl,71Ga35Cl,69Ga37Cl and71Ga37Cl. With these microwave data the constantsY 10 ≈ εe and —Y 20 ≈ ω e x e were determined. The parameters of the Dunham potentiala 0,a 1,a 2,a 3 andr e are given. The GaCl was produced by reaction of gaseous CCl4 with Ga evaporated at 1,500°C.
