Abstract

A new circular dichroism (CD) measurement system based on the detection of elliptically polarized light has been proposed. The approach has several unique and inherent advantages, such as sensitivities, reliability, and reproducibility, over conventional systems and Kliger’s pioneering work. We have rederived the Jones calculus and introduced the angular term into the formulation revealing that this approach should improve the signal intensity by controlling the light ellipticity. Therefore, we have first demonstrated the hypothesis by the quantitative analysis of the signal intensity measuring of the split CD pattern of tris(bipyridine)ruthenium(II) dichloride with the system. The CD signals increasing with decreasing the azimuth of retarder was clearly observed, enabling detection of CD signal with high sensitivity.
