摘要：
The rotational spectra of the 2SIGMA+ ground states of calcium monohydride and monodeuteride have been recorded in absorption between 250 and 700 GHz. The ps phase free radicals have been produced in a ceramic furnace by the reaction of elemental calcium with molecular hydrogen or deuterium in the presence of an electrical discharge. The molecular constants including the rotational constant, centrifugal distortion constants, spin-rotation constants, and magnetic hyperfine interaction constants have been extracted from the spectra.
