Sharp absorption
Webb11 sep. 2024 · Charge-transfer absorption is important because it produces very large absorbances. One important example of a charge-transfer complex is that of o-phenanthroline with Fe 2 +, the UV/Vis spectrum for which is shown in Figure 10.2.4 . Charge-transfer absorption in which an electron moves from the ligand to the metal also … Webb11 juli 2024 · The absorption and emission spectra of both 1 and 2 consist of a series of sharp peaks, corresponding to different vibronic lines.

Webb18 sep. 2024 · The formation pathway of aqueous-phase colloidal semiconductor magic-size clusters (MSCs) remains unrevealed. In the present work, we demonstrate, for the first time, a precursor compound (PC)-enabled formation pathway of aqueous-phase CdSe MSCs exhibiting a sharp absorption peaking at about 420 nm (MSC-420). The CdSe MSC … WebbNormally, the absorption spectra of metallofullerenes have long tails to the red down to 1,500 nm or more. The absorption spectra of the major isomers of mono-metallofullerenes M@C 82 (M = Y, La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Lu) are similar to each other and well represented by a sharp peak around 1,000 nm and a broad peak around 1,400 nm.
