Notes.

The wavelength intervals are those used for integrating the strongest neutral PAH absorption band systems.

The oscillator strengths are listed for the strongest neutral absorption bands and are taken from the literature:

Gudipati (1993),

Bito et al. (2000); Wang et al. (2003),

Rouillé et al. (2007),

Ehrenfreund et al. (1992).
