The infrared absorption bands of a representative polycyclic aromatic hydrocarbon (PAH) molecule, coronene, have been examined in the laboratory at various temperatures up to 240 C. This paper is devoted to a systematic analysis of the temperature variations of the integrated band intensity. A tentative interpretation of the observed behavior is given in terms of anharmonicity effects. These new laboratory results may be helpful in the context of the attribution of the 'unidentified' infrared band to PAH molecules. In addition, for the first time thermal-emission spectra of three different PAHs recorded at 240 C are presented.
