We can see color in the visible region of the spectrum (400-700 nanometers). If the light absorbed by something is visible, this absorption results in the COMPLIMENT of that color being seen by the human eye. For instance: if the wavelength is 400-424 nanometers, purple is absorbed, and the compliment (opposite) of it is yellow, so you see something that absorbs wavelengths 400-424 nanometers as YELLOW. When you plot value of light absorbed (Y-axis) vs. Wavelength of incident light (X-axis), lambda max is the tallest peak on the graph, explained: let's say that highest peak is at wavelength of 532, this means that most of the light absorbed is of wavelength=532 nanometers, which is green... the complimentary color to green is red... therefore, your eye will see red, not green.
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 value of anthracene is around 374 nm in the UV-visible spectrum. This corresponds to the wavelength at which anthracene absorbs light most strongly.
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.
The absorbance spectrum of a compound shows how much light it absorbs at different wavelengths. The lambda max, or maximum absorbance, is the point on the spectrum where the compound absorbs the most light.
The lambda max is 510 nm.
differnce between fluoresence and phosphoresence
The color of the jello would be the complimentary color of the absorbed light. For example, if you have red jello, that means it is absorbing green light, since green is red's complimentary color.
The reported UV lambda max of Vildagliptin drug is 254 nm.
257 nm
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.
uv max of pregabalin are following: 1.in water 276nm 2.in methanol 210nm
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
