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.
Mass spectrometry, UV/Vis spectroscopy, NMR spectroscopy CNMR spectroscopy, Infra red spectroscopy
Spectroscopy in the UV and visible wavelengths is used primarily to measure the electronic absorptions by conjugated electronic systems in organic compounds. However, many metals and salts can also absorb to some degree in the UV and visible portion of the electromagnetic spectrum (consider that visible spectroscopy is especially common in mineral spectroscopy, for example, to measure the color and spectral qualities of diamonds in jewelry). So, while UV-vis spectroscopy is used overwhelmingly for organic compounds, it can also be used for measurement of inorganic compounds.
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.
