✦ Synopsis

The assignment of the absorption spectra of 2-hydroxytropone (2-HT) is reported by measuring the circular dichroism spectra of the &cycIodextrin complexes \vith 2-HT and 2-H-f anion It is concluded that the fEst (270-400 nm) and second (210-270 MI) bands of 2-HT are respectively composed of two electronic transitions having perpendicular and parallel polarizations with respect to the long axis of 2-HT. Our results are in complete agreement with the-results obtained from the dichroic spectra of tropone derivatives in a stretched polyvinylalcohol sheet by Hoshi and Tanizaki.

## Abstract The binding isotherm of 2, 7‐di‐__tert__‐butyl proflavine on calf thymus DNA has been measured by dialysis equilibrium. The CD spectra of complexes of the dye and DNA have been measured, and the variation of the induced circular dichroism of the dye with the amount of dye bound (__r__)
