WebbThese blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Atomic number The number of protons in an atom. Electron configuration The arrangements of electrons above the last (closed shell) noble gas. Melting point The temperature at which the solid–liquid phase change occurs. WebbIn this study the ability of CF3 groups to bind electron rich side chains and backbone groups from proteins has been investigated by combining a Protein Data Bank (PDB) survey and ab initio quantum mechanics calculations. More precisely, an inspection of the PDB involving organic ligands containing a CF3 gro
