| Abstract: | The electric dipole moment of the X2σ+ state of Bal was measured using the molecular-beam laser-microwave double-resonance technique. From the analysis of the splitting and shift of rotational transitions in an electric field, the dipole moment of the vibrational ground state was determined as μ = 5.969(6) D (absolute error of the measurement in parentheses). The dipole moment predicted from an ionic bonding model is 6.14 D. |
