The experimentally measured radiative lifetimes and branching ratios were combined to determine the transition dipole moments for the B²Σ⁺(v = 0-3) - X²Σ⁺(v = 0-6) bands of aluminum monoxide, AlO, and compared with theoretical predictions. The B²Σ⁺-X²Σ⁺ (0, 1) band of a molecular beam sample of AlO was recorded at high spectral resolution both field-free and in the presence of static electric and magnetic fields. The ²⁷Al(I = 5/2) hyperfine interaction in the B²Σ⁺(v = 0) state was analyzed. The observed Stark shifts were analyzed to produce permanent electric dipole moments of 1.94(8) D and 4.45(3) D for the B²Σ⁺(v = 0) and X²Σ⁺(v = 1) states, respectively. It is demonstrated that the observed Zeeman spectra can be simulated using an effective Hamiltonian with the associated expected g-factors for both the X²Σ⁺(v = 1) and B²Σ⁺(v = 0) states.
