| Abstract | Polycyclic Aromatic Hydrocarbons (PAHs) are an important component of the Interstellar Medium (ISM). They are being used as probes for understanding of process and conditions of di erent astrophysical environments. The understanding of their IR spectra and its variations with PAH size and ionization state is useful in characterizing the ISM. Spectral features of model graphene sheets and also that of smaller PAH molecules are reported. The variation of intensity with charge state of the molecule shows that cations give a better correlation with observations. The relationship between changes in charge distribution with intensity changes upon ionization has been probed. |
