Question
1. Molecular and atomic absorption have two very distinct and different spectra. Explain these differences– diagrams and sketches can assist in the explanation.
2. Calculate the wavelength of light needed for an atomic absorbance process for an unknown material which requires 825 kJ/mol of energy to excite. Where in the electromagnetic spectrum is this light found? Most atomic absorbance processes between atomic orbitals occur in the UV/Vis region of the electromagnetic spectrum. Does the wavelength you calculated seem reasonable?
Explanation / Answer
Answer:
Atomic spectroscopy
Molecular spectroscopy
It majorly deals with atoms.
It majorly deals with infinite number of molecules.
Using this spectroscopy it is possible to find nature and amount of particular element in the sample.
Using this it is possible to find chemical nature and also the matter structure.
