The implications of orbital symmetry for a configuration's spin function are considered from the fairly general viewpoint required for multiconfiguration wave functions employing nonorthogonal orbitals. A general procedure is derived for the imposition of the spin constraints that may be necessary t
Forbidden transition probabilities are listed for ground term transitions of ions in the B I. F I, AI I and CI I sequences. Some of these transitions remain to be observed in flares. The isoelectronic sequences with outer configurations 2sZ2p, 2p 5, 3s23p, 3p 5 give rise to several well known coron
