โœฆ Synopsis

The IR and Raman spectra of a-and p-perylene crystal vibntions are investigated. p-perylcne is monomeric and ~-per> lene has face-to-face dimers. Frequencies and forms of the lattice vibrations as well as vibron relasation and localization are discussed. Polarization ratios in P crystals are perturbed by coupling to dimer vibrations.

The kinetic behaviour of the solid state thermal decomposition of dithionate to sulphate, M2[Sz0,] + M,[SO,], M = Na, K, has been studied by following the temporal decrease in the intensity of the Raman band arising from the v,(SO,) mode of [S2O6]". The sodium salt displays first order kinetics, but
