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

To calculate lambda max (λ max), generally used in spectrophotometry, you can use the formula: λ max = 1 / εmax, where εmax is the molar absorptivity (extinction coefficient) of the compound at its maximum absorbance wavelength. The λ max represents the wavelength at which the compound absorbs light most strongly.

How do you calculate lambda max of alicyclic chromophores?
To calculate the lambda max of alicyclic chromophores, you typically need to use computational methods like quantum chemical calculations or software tools like Gaussian or ORCA. These methods involve solving the Schrödinger equation to determine the electronic transition energies. The lambda max represents the wavelength at which the absorption of light is at its maximum for a specific alicyclic compound.

The lambda max is 510 nm.
What is lambda max for colorless proteins?
if the protein is colorless then it is quite tough to calculate the lambda max or absorption maxima directly (still you can check it by absorbtion maxima calculation/experiment). Otherwise, for its estimation first you have to treat it with any reagent (like folin reagent) then it will form a colored complex and then you can calculate it. For the common estimation of protein, there is a "Lowry Method" where you can calculate it on 750 wavelength.

Would you give me Examples for lambda max calculation?
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.
Lambda max of potassium dichromate solution in water?
The lambda max of potassium dichromate solution in water is typically around 350 nm due to the absorbance by the dichromate ion. This wavelength represents the maximum absorbance of light by the solution, providing information about its concentration and chemical properties. UV-Vis spectroscopy is commonly used to determine the lambda max of such solutions.
