Description
Summary:The Raman spectrum of powdered naphthalene has been measured at room temperature using 6328-Å He–Ne laser excitation and a double monochromator with photoelectric detection and digital recording. Eighty-six lines are observed, among them all the fundamentals assigned by Hanson and Gee [J. Chem. Phys. 51, 5052 (1969)] from Raman, phosphorescence, and fluorescence spectra. Using narrow slits (0.5–1 cm−1) several asymmetric and multiple lines are discovered and resolved into separate components. Five weak, very broad lines are discovered and interpreted as second-order lines or combinations of intramolecular and lattice vibrations. The width is determined for some of the lines. Intensities are given for all lines.
