Notes:
The Raman optical activity (ROA) spectra of some azo dyes binding to cyclodextrins have been measured. This appears to be the first successful attempt to measure the ROA induced in achiral molecules by intermolecular interaction with chiral molecules. There was no relationship between the ROA signals and the Raman shifts accompanying inclusion phenomenon. From comparison of the ROA spectra of methyl orange with α-cyclodextrin and congo red with γ-cyclodextrin, it seems that the ROA spectra reflect the difference in the positions of the SO3- groups in the guest molecules.
