-] In the case of polyacene molecules (i.e., C4n+2H2n+4), Tt electrons of the molecules can be treated as being delocalized along their circular paths. For the first few polyacene molecules, absorption regions are as follows: 7. Molecule Absorption region Benzene 255 nm Naphthalene 315 nm Anthracene 380 nm Naphthacene 480 nm 580 nm Pentacene Briefly explai the effects of a red shift (of absorption region) on chemical stability.
