Résumé

The only known example of hyperfine predissociation occurs in the I2 molecule. It has been extensively studied (1). Observation of a similar effect in Br2 is hindered by a strong rotational predissociation (αJ(J+1)) but the longer radiative lifetime of B3Π+Ou state of Br2 favors its detection at low J (1). With a supersonic Br2 beam the populations of low J values is enhanced. The excitation spectrum is obtained at ∼ 1 MHz resolution. The hyperfine structure of various lines display strong intensity anomalies. From the relations given in (1) we were able to determine the radiative lifetime and rotational and hyperfine predissociation parameters for some levels of the B3Π+Ou state of Br2
