Absorption Spectrum Using a Spectrophotometer

After using a spectrophotometer, I have obtained absorbance values. To create an absorption spectrum, should I convert these values to percentage absorbance? (I've seen it in textbooks as such)


If I were to convert absorbance to percentage absorbance, would I simply multiply all values by 100%?




This is simple mathematical conversion. Firstly, you find the fraction of each absorbance value. 


Let, the absorption spectrum has a three absorbance values say $A\_1, A\_2$ and $A\_3$. 


Now, find the fraction of each absorbance as per following:


fraction of $A\_1 = A\_1/(A\_1+A\_2+A\_3)$


fraction of $A\_2 = A\_2/(A\_1+A\_2+A\_3)$


fraction of $A\_3 = A\_3/(A\_1+A\_2+A\_3)$


Now convert all the respective fraction values into percentage as per:


percentage of $A\_1 = (\text{fraction of }A\_1 \cdot 100)\%$


percentage of $A\_2 = (\text{fraction of }A\_2 \cdot 100)\%$


percentage of $A\_3 = (\text{fraction of }A\_3 \cdot 100)\%$
