Hyperfine interactions in homonuclear diatomic molecules and u-g perturbations. I. Theory (1986)
Pique, J.P., Hartmann, F., Churassy, S., Bacis, R.
The hyperfine interactions in heavy homonuclear diatomic molecules are studied theoretically. The general matrix element of the related Hamiltonian is derived in the general case and detailed in the...
Pique, J.P., Hartmann, F., Churassy, S., Bacis, R.
The iodine B 0+u state is studied near its dissociation limit using sub-Doppler high resolution techniques. The recording of more than 10 000 hyperfine lines allows a systematic analysis of the...

Pique, J.P., Bacis, R., Hartmann, F., Sadeghi, N., Churassy, S.
Iodine exhibits the phenomenon of hyperfine predissociation, by which the different hyperfine sublevels of the same rovibronic level are given different lifetimes. This has been verified for the...

Hyperfine Predissociation in Br2 (1983)
J. B. Koffend, R. Bacis, S. Churassy, M. L. Gaillard, J. P. Pique, F. Hartmann
Hyperfine structure of several rovibronic transitions in the B-X system of B79r2 has been analyzed and the quadrupolar and nuclear spin rotation hyperfine coupling constants have been obtained. A...

J. B. Koffend, R. Bacis, M. Broyer, J. P. Pique, S. Churassy
Hyperfine structure for several E(0g+)–B(0u+) rovibrational transitions has been measured for the first time. Two single frequency lasers were used to excite E(0g+)(υ*, J*)–B(0u+)(υ′, J′)...
