✦ Synopsis

Line positions and emission probabilities of the Lyman and Werner band systems of molecular hydrogen have been calculated by solving a system of four coupled Schrödinger equations. We have been able to identify several thousand new lines emitted by a low pressure discharge in (\mathrm{H}{2}) from (172 \mathrm{~nm}) down to (78 \mathrm{~nm}). Many high-Jenergy levels are reported for the first time. Molecular constants are derived for the (unperturbed) ' II ({\text {" }}^{\text {is }}) states. Several examples demonstrate that the emission spectrum is very significantly different from that which could be deduced from a knowledge of only the absorption spectrum. co 1993 Academic Press. Inc.
