a solid stationary phase in which solute adsorbs to the side
Compare and contrast atomic and molecular spectroscopy.!
Atomic Spectroscopy is the measure of how atoms absorb/emit light. Emission and
absorbance band widths~.001 nm with no vibrational energy levels. !
Molecular Spectroscopy is the measure of how mol
Figure 1 shows the spectrum curve for the absorbance of Iron versus wavelength in the
experimental standards. This curve was used to identify the peak (maximum
wavelength) that was used as the light source wavelength for the spectrophotometer.
