## Abstract Compact expressions to calculate the transition energies, absorption line strengths, and rotational line strengths of circular dichroism for the excitonic states in a helical arrangement of __N__ identical chromophores are presented. The absorption spectrum __A__(__Ξ½__) and the CD spect

β¦ Synopsis
It is demonstrated that the helic-al arrangement of dye molecules dissolved in cholestcric phases leads to a strong circular dichroism in the wavelength range of the solute absorption bands This effect yields a simple method TV determine relative polarization directions of optical transitions.

The results of the "Chirality measurement" circular dichroism along different viewing directions within molecules and phases-the anisotropy of circular dichroism can give suitable information in order to check helicity rules or to analyze the suprastructural chirality of films of organic materials,
## Abstract We have measured the ultraviolet CD spectra for covalently closed and linear forms of phage PM2 DNA in solution. We find that increased concentrations of salt or ethanol (up to 50% ethanol by weight) depress the longβwavelength positive CD bands in the spectra of both forms of DNA, alth
The existence of circular dichroism in the triple differential cross section is shown for the emission of two electrons in the one-step double photoionization of a molecule. Our study reveals that the geometrical requirements for the presence of dichroic effects in the double photoionization of line
