Tailing absorption
Web15 Apr 2024 · Among these carbonaceous materials, the electromagnetic wave absorption properties of CNTs were early investigated because they possessed well-defined … WebThe excited-state absorption spectra of [Re (dpp) (CO) 3 Cl] and [ {Re (CO) 3 Cl} 2 (dpp)] have also been obtained and exhibit similar features as in the spectroelectrochemical measurements. The spectra are consistent with reduction of the α,α′-dimine ligand and are dominated by π→π* transition of the ligand radical anion.
