✦ Synopsis

The normal Raman spectra of trans-1,2-bis(dpyridyl)ethylene and its dihydrochloride and dideuterochloride salts are reported. Frequency shifts observed upon salt formation and deuteration are utilized in the assignment of vibrational modes. Additional assignments are made by comparisons to other pyridine-containing molecules and truns-stilbene. Assignment of the normal Raman spectrum of trans-1,2-bis(4-pyridyl)ethylene is essential to interpretation of the surface Raman spectrum of this molecule reported elsewhere [l].
