 Title    Thorexanthin, a New Carotenoid Pigment from the Caribbean Sponge Thorecta horridus  
 Abstract    The red-pigmented Caribbean sponge Thorecta horridus contains thorexanthin (3-m ethoxy-/?-;f-caroten-4-one) as a new carotenoid pigment. Its structure was determined by spectroscopic methods, including 2 D N M R experiments.

 Title    Structure and Conformation of Photosynthetic Pigments and Related Compounds 3. Crystal Structure of ß-Carotene  
 Abstract    The crystal structure o f the title compound (C40H 56, M w = 536.8) has been redetermined by X-ray diffraction methods in order to achieve a structure at higher resolu­ tion suitable for theoretical calculations. The crystal sys­ tem is monoclinic, P2 ,/«, a = 7.656(2), b = 9.445(5), c -23.536(15) Ä , ß = 93.41(2)°, V = 1698.8(15) Ä 3, Z = 2, D = 1.050 m g/m 3, 130 K. R = 0.071, R w = 0.076.
