INFRARED AND RAMAN SPECTRA OF FURAN, PYRROLE, AND THIOPHENE

Abstract

The infrared and Raman spectra of furan, pyrrole and thiophene in the liquid state and the infrared spectra in the gaseous state have been obtained with greater resolution and/or over a greater range than previous data. The effect of the additional data on previous vibrational assignments is discussed. Certain band contours have structure other than the P-Q-R envelope. Possible explanations for this additional structure are discussed.
