Norm&coordinate calculations are carried out on a simple model of a cross link in trans-polyacetylene (P-4)\_ The results indicate the need for a reanalysis of the presently accepted vibrational assignment of trans-PA and suzest the need for a more tborougb chemical study of purposely cross-linked P

## Manganese(V)do crystals of Bas(PO,)sCl (apatite structure) and Ca,VO,CI (spodiosite structure) exhibit highly resolved photoluminescence in the near-infrared. It is assigned to intraconfigurational 'E -+'A2 (Td notation) transitions, and the vibrational sideband structure is interpreted in term
