The sub-Doppler laser induced fluorescence spectra of numerous branch features in the B +2 -X +2 (0,0) band of calcium monodeuteride were recorded field-free and in the presence of a static electric field of up to 7 kVcm. The field-free spectra were analyzed to produce an improved set of fine structure parameters for the B +2 (v=0) state. The observed electric field induced splittings and shifts were analyzed to produce permanent electric dipole moments of 2.57(3) and 2.51 (3) D for B +2 (v=0) and X +2 (v=0) states, respectively. The permanent electric dipole moment for the X +2 (v=0) state of CaH is estimated to be 2.53 (3) D.
