Speeds up reaction by giving the reaction a new path.. The new path has a lower activation energy.. Why is:. Mn. 2+. (. aq. ) colorless. Cu. 2+. (. aq. ) less deeply blue colored than Cu(NH. 3. ). 4. 2+. Zn. 2+. (. aq. ) colorless. MnO. 4. -. deeply colored. W(CO). 6. colorless. Sigma Interaction Strength. 2. UV Spectroscopy. Introduction. UV radiation and Electronic Excitations. The difference in energy between molecular bonding, non-bonding and anti-bonding orbitals ranges from 125-650 kJ/mole. This energy corresponds to EM radiation in the ultraviolet (UV) region, 100-350 nm, and visible (VIS) regions 350-700 nm of the spectrum. Why is:. Mn. 2 . (. aq. ) colorless. Cu. 2 . (. aq. ) less deeply blue colored than Cu(NH. 3. ). 4. 2 . Zn. 2 . (. aq. ) colorless. MnO. 4. -. deeply colored. W(CO). 6. colorless. Sigma Interaction Strength. Mott vs. Mott-Hubbard Transitions. Role of Lattice vs. Electronic Subsystems. Presence of intermediary phases. Trigger-dependent excitation pathways. Electron/hole doping. Heating. Structural distortions. Spectroscopy . . Is the interaction between matter and electromagnetic radiation (light). . Spectroscopy is commonly used in chemistry to detect, identify, and quantify information about different atoms and molecules. . Purpose of this course – understanding the diagram below:.

Department of Mechanical Engineering. November 2011. 1. What is LMIS ?. In . a . Liquid metal ion source (LMIS). , a metal (typically gallium) is heated to the liquid state and provided at the end of a capillary or a needle. Then a Taylor cone is formed under the application of a strong electric field. As the cone's tip get sharper, the electric field becomes stronger, until ions are produced by field evaporation. These ion sources are particularly used in ion implantation or in focused ion beam instruments..
