The lambda max is 510 nm.
using uv-visible spectrophotometer concentration vs absorbance is plotted and the maximum absorbance of the drug is lambda max of the drug. then after it will decrease. still if needed clarification, refer beer lambert"s law
236nm
254 nm
to ensure maximum absorbance of light by the solution
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.

uv max of pregabalin are following: 1.in water 276nm 2.in methanol 210nm
254 nm
The base value of this structure is 253 nm. There are 4 alkyl substituents which add a value of 20 (4x5 nm). So the lambda max of this structure is 273 nm.
