Light absorption of polydiacetylene chains has been investigated using Green's function. In tight-binding approximation, we defined a Hamiltonian at first, then computed two-electron Green's function using random phase approximation, discussed some properties of excited-states for PDA's, calculated light absorption spectra and compared with experiments.
