Abstract

Data on vibrational spectra of polycyclic aromatic hydrocarbons in gas phase are of considerable interest for solving the astrophysical problems. Results of experimental and theoretical investigations of spectral characteristics: positions, widths, absorption cross-sections and oscillator strengths of anthracene molecule bands in the 800 - 3200 cm ^-1 region are given. Comparison of experimental and calculated intensity distribution in a separate absorption band of anthracene vapors shows that a decisive factor in forming a profile is free rotation of molecules.
