 Title    H elm u t  
 Abstract    The striking similarities of the hypsochromic shifts of the longest wavelength absorption o b ­ served in the serie 1—3 and 4 —6 are rationalized by means o f sim ple molecular orbital theory.

 Title    Kristall-und Molekülstruktur von 2-[3-(N,N-Diethylammonium)propylimino]-2-phenyl-dithioacetat Crystal and Molecular Structure of 2-[3-(N,N-Diethylammonium)propylimino]-2-phenyl-dithioacetate  
 Abstract    The title compound, formed by the reaction o f acetophenone with 3-diethylamino-1-propylamine and sulfur, crystallizes in the orthorhombic space group P 2 12 12 1 (Z = 4) with lattice constants a = 818.1(2) pm, b -1225.1(2) pm and c = 1622.4(4) pm. The characterization of the molecule as a zwitterion is established by the observed bond parameters. Both spec­ troscopic investigations and the results of the X-ray structure determination show that a hydrogen atom is bonded to the amino nitrogen rather than to the imino nitrogen.
