uv max of pregabalin are following:
1.in water 276nm
2.in methanol 210nm
The reported UV lambda max of Vildagliptin drug is 254 nm.
Wavelength lambda and frequency f are connected by the speed c of the medium. c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f
We got the formula: speed of medium c = frequency f times wavelength lambda. f = c / lambda lambda = c / f c = 343 m/s at 20°C or 68°F in air. For f = 350 Hz lambda = 343 / 350 = 0.98 meters
EM waves travel at the speed of light in a vacuum. c=f*lambda where c is the speed of light, f is the frequency of the way and lambda is the wavelength. Lambda= c/f = (3x108 m/s)/3x1010 s-1) = 1x10-2 m or 1 cm

The lambda max of paracetamol typically occurs around 243 nm in a pH 6.8 phosphate buffer.
The lambda max for benzene is approximately 255 nm.
The lambda max of S-adenosyl-methionine in UV spectrum is around 260-265 nm.
The lambda max value of anthracene is around 374 nm in the UV-visible spectrum. This corresponds to the wavelength at which anthracene absorbs light most strongly.
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.
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
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.
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.
Lambda max is an intrinsic property because it is a characteristic wavelength specific to a particular molecule. It represents the maximum absorbance or emission of light by that molecule and is determined by its electronic structure.
