Tengo mucha experiencia con:
AA/AEespectroscopía de Absorción Atómica / Emisión Atómica
ESR (Resonancia electrón-espín) espectroscopía
espectroscopía de fluorescencia
FT-IR espectroscopía infrarroja por Transformada de Fourier
GC/MS (Cromatografía de Gases/ Espectrometría de Masas)
HPLC (La Cromatografía de Alto Rendimiento para Líquidos)
RMN espectroscopía de Resonancia Magnética Nuclear
UV-V espectroscopía en la región ultravioleta-visible
How did I get this experience? I taught dozens 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
26 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.
