Rcsonrmce Ramman spectm of single ctyfals of the organic metal ThlAlTCNQ eshibit strong resonances from the 1; ions. Overtones up to u = 5 were readily observed. Temperature-dependent measurements reveal a sharp discontinuity of the fundrtmcntrd intensity and of the linewidth of the fiirt overtone a

Effects of the phase transition between the high-temperature tetragonal phases of the CsScF 4 crystal were studied by Raman scattering. The appearance of new lines including a soft mode was observed below the phase transition point, in complete accordance with the new crystal symmetry. The behavior
The synthetic polymer poly-L-proline exists in two conformational forms, I and 11, the structures of which have been elucidated by x-ray crystallography.'-3 Form I is a right-handed helix with all peptide bonds in the cis configuration, and is stable in pyridine and aliphatic alcohols. Form I1 is a
