Advantage: non-destructive to the sample
Disadvantage: High detection limit
Mass spectrometry, UV/Vis spectroscopy, NMR spectroscopy CNMR spectroscopy, Infra red spectroscopy
disadvantages - radiation can ionize and damage cells and is very expensive to use. advantages - can go in lots of detail, and results are usually very clear
Woodward Fieser rules are a set of emperical rules to calculate lambda max. in UV spectroscopy theoretically. They can be used to calculate the wavelength of maximum absorption of dienes and conjugated carbonyl compounds.
A wavelength vs absorbance graph depicts in uv spectroscopy shows the different colored wavelenths of UV light and how they are absorbed and percieved, and which ones are visible and which ones are not.
Each compound has a specific absorption spectra.

Because nonmetallic elements are in vacuum UV
