Circular dichroism from single plasmonic
WebHere, we define circular dichroism as the reflection difference between the LCP and RCP incidences, such that CD = R RCP – R LCP. Surprisingly, a change in the twisted angle only leads to the modification of the amplitude of CD signals of the quasi-BIC resonances whereas the resonance wavelengths and Q -factors stay stable (Figure 4d,e ). WebDec 10, 2024 · Chiral recognition is of fundamental importance in chemistry and life sciences and the principle of chiral recognition is instructive in chiral separation and enantioselective catalysis.
