Raman Spectrum of Anthracene

Abstract

Raman spectra of the anthracene solution are recorded using a Raman source of high luminosity. Twelve new frequencies are found and an assignment is proposed using earlier measurements on a single crystal.

Single Dibenzoterrylene Molecules in an Anthracene Crystal: Spectroscopy and Photophysics

“…Figure 6 shows the fluorescence spectra of a single DBT molecule in the main site (upper part) and of one in the red site (lower part) plotted as functions of the frequency relative to excitation. We did not find any Raman scattering lines of the Ac crystal [38] in these spectra. As mentioned previously, the detection filter transmits lower relative frequencies from the red site than from the main site with respect to the excitation light.…”

Efficient light-to-current conversion by organic–inorganic interfacial charge-transfer transitions in TiO2 chemically adsorbed with 2-anthroic acid

“…1360 cm −1 ). This vibrational structure is attributed to the symmetric C C vibrational mode in the anthracene moiety [21]. TiO 2 nanoporous films before the immersion show inter-band absorption in the near UV region, reflecting the wide band gap of ca.…”

Resonance Raman and Surface‐enhanced Resonance Raman Spectroscopy of Hypericin

“…SERRS spectra contain bands at 1359 (457.9 nm excitation), 1343 (488 nm excitation) and 1342 (514.5 nm excitation) that are not present in the RR spectra. These bands are in the region of C-C in-plane stretching modes (Abasbegovic et al, 1964;Dollish et al, 1974). The similarity between the spectra indicate the absence of strong chemical interactions between the Ag surface and hypericin.…”

“…The band at 1331 cm-' by comparison to PQ is a C-C in-plane bending vibration of the outer benzene fragments and the 1370 cm-I band is due to in-plane vibrations of the central fragment, the portion of the molecule containing the carbonyl group (Gastilovich et al, 1986). Bands between 1160 and 1100 cm-I are from C-CH in-plane bending modes and bands in the region from 1030 to 680 cm-I are due to C-C inplane bending vibrations (Abasbegovic et al, 1964;Dollish et al, 1974;Lehmann et al, 1979;Dutta and Hutt, 1987).…”
