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.
actually captopril is a PH sensative drug, as per IP-in 0.1N HCL it's showing 212nm, and it's very difficult to find out lambda by UV-spectroscopy because the UV visible range of UV- is 200-400nm, and generally near to 200nm all lambda consider as solvent pick....so UV-spectoscopy is not perfact one for analysis purpose of captopril.
Each compound has a specific absorption spectra.

1 infra-red (UV-VIS) spectroscopy. 2 proton magnetic resonance spectroscopy. 3 carbon 13 magnetic resonoce spectroscopy.
The study of high-energy, electromagnetic radiation, which includes x-rays, is called atomic spectroscopy. The study of nuclear radioactivity and decay is called nuclear physics. For the study of electromagnetic radiation of energies below x-rays you have: UV - UV spectroscopy Visible Light - gaffer Infra-red - infrared spectroscopy Microwave - microwave spectroscopy Radio - amateur broadcaster

Spectronic 20 was also an UV-Vis spectrophotometer.
