  In this work, we have studied the permanent electric dipole moments of singly
charged aluminium monohalides in their electronic ground state, X$^2\Sigma$,
using Kramers-restricted relativistic configuration interaction method. We
report our results from this method in the singles and doubles approximation
with those of Dirac-Fock calculations. For our finite field computations,
quadruple zeta basis sets were employed. We discuss the electron correlation
trends that we find in our calculated properties and have compared our results
with those from literature, wherever available.
