✦ Synopsis

The fundamental features of the induced optical activity in dye-helix complexes are clarified by the trap potential model. The effect of the potential depth on the induced rotational strength is explained in terms of the relative magnitudes of the wave-phase and helix-phase variations in the path of an electron moving along a restricted helix segment just like an exciton trapped around a dye intercalation site. The potential parameters have been optimized so as to reproduce the ionic strength effect upon the rotational strengths induced in proflavine-DNA intercalation complexes.

The fluorescence excitation and dispersed fluorescence spectra of the complexes of p-dtmethoxybenzene with various non-polar and polar solvent molecules prepared by supersomc expansion have been measured. It was found that only the cis isomer of the molecule selectively forms the complexes with the
