Molecular dipole moments (μ) and polarizabilities (α_i) of NMA and ACEM. $\overline{\alpha }$ is the trace of the polarizability tensor. Δ₁α and Δ₂α are invariant measurements of polarizability. Dipole moments are in Debye and polarizabilities in ų. QM values were determined at the MP2/aug-cc-pVDZ level.
