Temperature dependence and pressure dependence of the vibrational properties of corannulene

Résumé

Herein, we report the experimental investigation of the vibrational properties of corannulene using Raman spectroscopy. The temperature dependences of the Raman spectra between 300 and 20 K reveal a very high sensitivity of the low frequency domain between 40 and 200 cm(-1) compared to the intramolecular domain. The behavior of the Raman modes of the corannulene under pressure, between 0.53 GPa and 8 GPa, is also studied. Under pressure, in the intermolecular vibrational domain (<150 cm(-1)), two transitions occur suggesting metastable intermediate stages under pressure. (C) 2008 WILEY-VCH Verlag GmbH & Co.
