Vibrational Spectra and Assignment of Naphthalene and Naphthalene-<i>d</i>-8

Abstract

Infrared and Raman spectra taken of samples of naphthalene-d-8 of high deuterium content are reported. These spectra along with spectral data on naphthalene have been used to make an assignment of frequencies to the normal modes of vibration for this molecule. Although this assignment represents a significant contribution towards a correct one and provides good agreement with the experimental thermodynamic data, it still contains a number of tenuous points.
