Energies are given in cm\(^{-1}\). See this link for conversion factors. Electric matrix elements are given in atomic units. Magnetic dipole matrix elements are given in Bohr magnetons, \(\mu_B\). The values of magnetic-dipole hyperfine constants A are listed in MHz. Dipole polarizabilities \(\alpha\) are given in atomic units, \(a_0^3\), where \(a_0\) is the Bohr radius. The atomic units for \(\alpha\) can be converted to SI units via \(\alpha /h \rm{[Hz/(V/m)^2]}\)\(=2.48832 \times 10^{-8} \alpha \) [a.u.], where the conversion coefficient is \( 4\pi \epsilon_0 a^3_0/h \) and the Planck constant \(h\) is factored out.
