Based on AM1 and INDO/CI methods, using the program for calcns. of the nonlinear optical second-order susceptibilities (bijk), (bijk) and (bm) were calculated for (CH3)2N(C6H4)nCN series mols., n = 1 ?6. A systematic study is reported of the effect of conjugation length on the mol. nonlinear optical second-order susceptibilities and investigated the laser frequency dependences (dispersions) of (bm) are discussed.
