Why are molecular absorbance spectra broad, while atomic absorbance spectra are narrow (“lines”)? What are the major components of an absorbance instrument and what are their roles in spectral acquisition? Are absorbance measurements more qualitative or quantitative in nature (what useful information can we get from them)?
