A proposal for the solid-state structure of poly(p-phenylene isophthalate) with oxydecylperfluorodecyl side chains is presented, which was calculated by the new Rietveld refinement program BGMN. A triclinic unit cell with a Ο 0.575 nm, b Ο 4.06 nm, c Ο 2.1 nm, β£ Ο 91.2Β°, β€ Ο 85.7Β°, and β₯ Ο 66.1Β°was
Current observations on heteroxanthln (obtained from Trlbonema and Vaucherla) provide further support for the structure as 3,5,6,3'-tetrahydroxy-5,6-dlhydro-7',81-dldehydro-@-carotene. Recently, two different molecular structures have been proposed for hetero-
