✦ Synopsis

The Raman spectra of molecular complexes of (512 and BIG with NH3. pyridine, methyl-and ethylamines have been obtained at low temperatures.

Frequency shift and intensity increase of the halogen bands have been observed at complexation.

The normaI coordtiates

have been calculated for the pyridine-halogen complexes using a linear triatomic model,

R;?mnn spectra of liquid mixtures of TCNE with aromatic tlecWm donors were studied. Red-shifts up lo 20 cm-' and changes in the intensity ratio of the C=C and C=N stretching modes of TCNE from 0.5 to 1.5-3.0 upon complexation were observed and related to an electron transfer of up to 9 % in the Boun
