In poly(1-vinylnaphthalene)(P1VN) and poly(2-vinylnaphthalene)(P2VN), conformational energies of meso and racemic dyads were computed as functions of skeletal bond and side group rotations (0°(<I>o</I>) or 180°(π)). The calculation was carried out according to the truncation procedure proposed by D.Y.Yoon. The backbones in P1VN and P2VN were limited to just two rotational states, trans (t) and gauche (g) conformation. The steric interactions involving the bulky naphthyl group precluded \barg conformation; a similar situation occurs in polystyrene. Numerical results suggested these conclusions: the excimer forming site conformations for P1VN were meso : tt(ππ) and racemic : tt(ππ) states, and for P2VN were meso : tt(ππ), tt(<I>oo</I>), tt(<I>o</I>π), and tt(π<I>o</I>) states. These conformations could also be correlated to the dual emissions observed in P1VN and P2VN.
