II.F.1 Atomic Emission Spectroscopy (AES) Early AES instruments were rather straightforward and excited the atoms in a sample by placing the sample in a carbon arc. The resulting light was passed through a diffracting prism, or across a diffraction grating, and the resulting light spectrum was...
This process is called emission. A spectrum is the wavelengths of light either absorbed or emitted by an atom or molecule. The spectrum, which corresponds to transitions between electronic energy levels, is unique. This allows us to identify atoms based on their spectrum. Atomic Absorption ...

, we define the pair of Fe atoms (Fe2-N6) that can be most efficiently anchored by the urea ligand as neighboring Fe atoms. These Fe atoms are separated at a distance of about 0.29 nm. The Fe atoms with longer distances are denoted as isolated Fe atoms. We used this definition ...
