text: Carbonaceous material would have accreted together with the planetesimals that formed the planet (see section 1.2 for a summary): there is a wide range of carbonaceous particles in the interstellar medium ranging from amorphous carbon to polycyclic aromatic hydrocarbons (PAHs), and even more complex molecules such as fullerenes (ball-shaped molecules composed of 60, 70 and more C atoms arranged in rings); these molecules and, additionally, C 2 H 6 , N 2 + and CO + occur in comets, whereas carbonaceous meteorites contain a large variety of organic particles including amino acids that do not occur on Earth (Ehrenfreund and Menten, 2002).
