 Title    Darstellung und Eigenschaften von Monofluoramin, H 2 NF Preparation and Properties of Monofluoramine, H 2 NF  
 Abstract    Monofluoramine H ; NF is prepared by thermolysis of H 3 NF + HF 2 ~ -nHF and selective absorp-tion of HF on activated KF. In the solid state H 2 NF is stable below 170 K, and immediately decomposes in NH 4 HF 2 " and N 2 by melting.

 Title    Darstellung von SC12F+MF6 (M = A s, Sb) und zusammenfassende  
 Abstract    Betrachtung der Kationen SC1"F3_IJ+ (n = 0 —3) [1] Preparation of SC12F +MF6~ (M = As, Sb) and a Comprehensive Discussion of the Cations SC1"F3_"+ (n = 0 -3) [1] The preparations and characterizations of com pounds SC12F +M F6" (M = As, Sb) are reported. They are yellowish hydrolysable solids, with a strong tendency towards sym metrization in solu­ tion. The mass spectra data indicate the form ation of SC12F2 on thermolysis. The series of SCl"F3_n+-cations (n = 0 —3) is now com plete, and a comprehensive discussion of the spectro­ scopic data is given.

 Title    Spectra and Decay Kinetics of Diadamantyl-Dioxetane Chemiluminescence  
 Abstract    The thermal decomposition of 1,2-diadamantyldioxetane was studied by kinetic and spectroscopic methods. Spectra of the chemiluminescence emitted during the thermally induced decomposition of 1,2-diadamantyldioxetane, tetramethyldioxetane and tri-methyldioxetane were obtained and the influence of quenchers and radical-scavengers, and the presence of "heavy atoms" in the surrounding of the emitting species was investigated. The kinetics of the decay mechanism was followed by measuring the time dependence of the chemiluminescence. The influence of radical-scavengers, quenchers and "external heavy atoms" on the kinetics was assessed. Experimental results were discussed in terms of a biradical decay mechanism.

 Title    Darstellung von einigen Phenyldicarboxylatostibanen Syntheses of Some Phenyldicarboxylatostibanes  
 Abstract    Som e phenyldicarboxylatostibanes of the general formula C6H 5S b (O C -R) ; were synthesized O by simple m etathesis reactions from phenyldiethoxystibane and carboxylic acids in the ratio 1:2. By reaction o f 1,2-dicarboxylic acids with phenyldiethoxystibane in the ratio 1:1 phenyldicarboxyl­ atostibanes are also obtained. Som e properties and the 'H NM R spectra o f these com pounds are described, IR data are reported and discussed.

 Title    X-Ray Structural Analysis and Vibrational Spectra of Sodium Cysteine-S-sulfonate, +H3N C H (C 0 0 )CH 2S 20 3Na -3 /2 H 20 [1]  
 Abstract    The title com pound crystallizes orthorhombically (space group C 222,) with a = 797.0, b = 870.3 and c = 2739.0 pm. The anions are zwitterions which are heavily involved in intra-and intermolecular NH --O and OH -O hydrogen bonding. The two types o f sodium cations are coordinated by six oxygen atoms each o f which belongs to either S 0 3 groups (N a 2) or water molecules and S 0 3 groups (N a l). A second type o f water molecules is not coordinated to the cations. The SS bond length is 208.2 pm. Infrared and Raman spectra o f the title com pound are reported and tentatively assigned. The SS stretching vibration is observed at 409 cm -1.
