Instrumentation Skills:

I have substantial experience with:


See the instruments themselves here.

How did I get this experience? I taught hundreds of undergraduate and graduate students in the chemistry department of a large American University. And I used these techniques myself in research that has produced 28 papers to date.

These techniques often use different parts of the electro-magnetic spectrum. One can think of it as using different "colors" of light.

    AA/AE uses visible light.
    ESR uses microwaves.
    Fluorescence uses ultraviolet light.
    FT-IR uses infrared.
    NMR uses radio waves.
    UV-Vis uses ultraviolet and / or visible light.


The techniques look at different events (things that happen) in the atom or molecule:

    AA/AE looks at electrons jumping levels in an atom.
    ESR looks at electrons changing spin levels in a molecule.
    Fluorescence looks at electrons relaxing from highly excited vibrational states in S1 (with rare exceptions) to S0 in a molecule.
    FT-IR looks at changes in vibrations in molecules
    NMR looks at changes in spins levels in the nucleus of the atoms of a molecule
    UV-Vis looks at electrons jumping levels in a molecule.
