The molecular-beam, laser--rf, double-resonance technique has been used to make high-precision measurements of the spin--rotation and hyperfine interactions in the X /sup 2/..sigma.. (v = 0) electronic ground state of Ca/sup 79/Br and Ca/sup 81/Br. The spin--rotation interaction is found to have a strong N dependence. The Frosch--Foley magnetic hyperfine parameters b and c and the electric--quadrupole hfs parameter eqQ are determined for both molecules.
