If you have a spectrofotometer ( the thing to mesure the absorbance) then play with the setting and use a maximum. this will lay close to your specific absorbance or take the pharmacopea or a MERCK index
In UV spectroscopy, the baseline refers to the horizontal line at zero absorbance on the absorbance axis. It represents the reference point for measuring the absorbance of the sample. The baseline should be stable and noise-free to ensure accurate measurement of the absorbance of the sample.
because that chart gives a more accurate value than the absorbance scale on the specthometor
You need a graphic concentration versus absorbance.
Absorbance and optical density (OD) are often used interchangeably to describe the light absorbance properties of a substance. However, technically, absorbance refers to the logarithm of the ratio of the intensity of light incident on a material to the intensity transmitted through the material, while OD specifically refers to the absorbance measured in a spectrophotometer at a specific wavelength.
A sabin is a unit of measurement which measures the absorbance of sound of a material.
specific absorbance- it is absorbance in a solution containing one gm of substance in 100 ml solvent in 1cm shell. so it is having a difference with absorbance which is negative logarithm of incident light to the transmitted light. divya.chakraborty@gmail.com
"absorbance"Since in the experiment, you probably choose the wavelength, then measure the absorbance (absorption?, the absorbance is the dependent variable.
Blank Sample in Spectrophotometry is used to measure the absorbance of light without sample. It is subtracted from the total absorbance for measurement of Absorbance from a sample's absorbance.
Absorbance is a measure of the amount of light absorbed by a sample at a specific wavelength, typically measured using a spectrophotometer. Concentration is the amount of a substance present in a unit volume of a solution, often expressed in moles per liter (M). The relationship between absorbance and concentration is governed by Beer's Law, which states that absorbance is directly proportional to concentration and path length.
Absorbance is considered a continuous variable.
in primary light absorbed by outer molecule while in secondary re-absorbance occurs
UV cut-off is the wavelength at which the solvent absorbance in a 1 cm path length cell is equal to 1 AU (absorbance unit) using water in the reference cell. ( © 2000, LC Resources Inc.)

In spectrophotometry, optical density (OD) and absorbance are directly related. As the OD increases, the absorbance also increases. This means that a higher OD value indicates a higher absorbance of light by the sample being measured.
