 Title    Correlation of Mössbauer Quadrupole Splitting ( zI/?q) and Infrared Cyanide Frequency Separation in Alkali Metal Ferricyanides  
 Abstract    Mössbauer and infrared spectra of the alkali metal ferricyanides M* [Fe(CN)6] • n H 20 , where M1 = H , Li and N a were studied at room temperature. All the three compounds displayed a doublet with small quadrupole splitting (AEq). Infrared spectra of these compounds in solid state gave two frequencies for C = N stretching vibrations with their separation (Av) in increasing order which was found to be linearly correlated with AEq. A plausible explanation has been given in terms of the interaction of Li+ and Na+ cations w ith the CN-ligands of octahedrally symmetric ferricyanide anion [Fe(CN)6] 3-similar to that of hydrogen atoms which are hydrogen bonded in H 3Fe(CN)6.

 Title    H-NM R-und IR-spektroskopische Untersuchungen zur Konformation von Hydroxy - methyl-Substituenten in 2.3-Stellung an Hexachlorbicycloheptenen

This is caused both by hindered rotation and the asymmetry of the molecules. For some molecules the spectroscopic data allow conclusions to be made concerning the con­ formation of the substituents.
