摘要：

Using Doppler-free polarization spectroscopy, the hyperfine structure of the B-X system of 79Br2 was measured for the levels B3Π0, v′ = 16-28, and X1Σg+, v″ = 1, 2. Besides the nuclear electric quadrupole coupling, the magnetic spin-rotation interaction was analyzed, which varies strongly with the vibrational energy of the electronically excited state. This behavior originates from a perturbing repulsive state Ω = 1u, the potential of which can be estimated in this way. © 1991.
