The predissociation of H2 molecules in the 3prr D ' KI", state has been studied by Farm-profile and~sis of the Rs have been measured. Stron, 0 indication of the opening of a new channel of dissociation is reported\\_ Coupling with the B"B t Z: state may be responsible for this.
The electronic non-diagonal Born-Oppenheimer coupling matrix elements between the molecular h?drogen DIE, state and the B' L Zu end B 1Z; u states were calculated in the Hartree-Fock approx-imztion at R= 1.0,1.2,1.6 and 2.0 au. These were used to calculate the predissociation widths for the v = 3 to
Cl calculations for the Swan and Fox-Henberg band intenutles III C2 are reported and excellent agreement with euperimental values is found. The X IReI' values vary strongly with bond drstance and in ~ertarn C;IWS az~ found to depend ng-ruticantl~ on the length of the Cl eupmslon.
The emission cross sections have been measured for the diagonal Fulcherdl bands (3p311u, u'+ 2s3Z& IJ" with u'= u"= 0, 1,2,3) in Ha by means of electron impact. Prom these the excitation cross section for the 3p3$, state has been dctermined. We found a maximum value of 4.2 (k 0.8) X 1O-'8 cm2 at 15.
