摘要：

We present an ensemble of experimental studies and calculations about the lifetimes and predissociations in the B state of the Cl2 molecule. The radiative lifetime is shown to be very long (tau-v = 12-congurent-to 1.2 ms), in accordance with the previously determined and confirmed value of the B-X transition dipole moment. Our measurements of lifetimes for (J = O, upsilon greater-than-or-equal-to 13) show the existence of a hyperfine predissociation of these states. Finally a simple model of the first OMEGA = 1u states of Cl2 is given which explains, within a factor of 2, the gyroscopic predissociation of the B 3-PI-O(u)+ state by the A 3-PI-1u and 1-PI-1u states.
