We present experimental and theoretical studies of the vibrational properties of two similar polymers containing phenyl rings: poly(p-phenylene)sulfide (PPS) and poly(p-phenylene)oxide (PPO). We have investigated these compounds by using the Resonant

We have performed a Raman spectroscopic investigation on 13 C enriched BEDT-TTF molecules which has been motivated by isotope shift experiments of the superconducting transition in the s H phase of (BEDT-TTF) 2 I 3 (T c ≈ 8.2K at mid transition) st

First-order Raman spectra of CsF (F centres) studied in resonance with the F band (610 and 640 nm) at T = 10 K are described. The acoustic (43, 48, and 76 cm−1) and optical (135 and 137 cm−1) modes are due to electron-phonon interactions involvin

Experimental Raman spectra of Na I containing F -centers are described and compared to the calculated spectra, in the off-resonance approximation. The position of the strong resonant mode, almost of A 1 g symmetry, is interpreted using a decrease of
