The interplay of the relativistic and correlation effects in the permanentelectric dipole moments (PDMs) of the X2{\Sigma}+ ({\nu} = 0) electronic groundstates of the alkaline earth monoflourides (BeF, MgF, CaF, SrF and BaF) hasbeen studied using a relativistic coupled cluster method (RCCM). Thecalculations were carried out using double, triple and quadruple zeta basissets, and with no core orbitals frozen. The results are compared with those ofother calculations available in the literature and with experiments. Thecorrelation trends in the PDMs of these molecules are discussed in detail.
