    "abstract": "This paper is a theoretical work in support of a newly proposed experiment\n(R. Stutz and E. Cornell, Bull. Am. Soc. Phys. 89, 76 2004) that promises\ngreater sensitivity to measurements of the electron\u0027s electric dipole moment\n(EDM) based on the trapping of molecular ions. Such an experiment requires the\nchoice of a suitable molecule that is both experimentally feasible and\npossesses an expectation of a reasonable EDM signal. We find that the molecular\nions PtH+, HfH+, and HfF+ are suitable candidates in their low-lying triplet\nDelta states. In particular, we anticipate that the effective electric fields\ngenerated inside these molecules are approximately of 73 GV/cm, -17 GV/cm, and\n-18 GV/cm respectively. As a byproduct of this discussion, we also explain how\nto make estimates of the size of the effective electric field acting in a\nmolecule, using commercially available, nonrelativistic molecular structure\nsoftware.",
