The object of the present investigation was to study the Raman spectrum of the monomer in the solid state at — I8o°C in order to find out whether in the solid state the monomer undergoes any change similar to that observed iu the case of polymerization and also to verify whether the line 1598 cm-1 is actually present in the Raman spectrum of the polymer. [...] Of course in the case of the polymer there are lines at 238 300 and 2962 cm-1 and it might be suspected that the extra lines observed in the case of the liquid might be due to partial polymeri zation of the liquid during the exposure. [...] The diminution of intesity of the line 164o cm" with solidification and lowering of temperature of the monomer thus indicates that the C=C bond is transformed into C—C bond in some of the molecules in the solid state probably owing to formation of new bonds between some of the adjacent molecules. [...] The appearance of the new Raman line 58 cm-1 in the case of the solidified monomer may further indicate the formation of dimers in the solid state. [...] this shows that the broadening is not mainly due to the random orientation of the molecules because in the case of the solid the arrangement of the molecules in the lattice is regular.
