In most research papers the wavelength chosen for DBT detection is 284nm, but according to the NIST data the maximum absorbance occurs around 230-240nm. Can anyone explain why it is so?
Desulfurization, Oxidation, Sulfur compounds Dibenzothiophene UV/Vis
Dear Satadru,
Detectability is not the only parameter to have in mind in UV-Vis spectrophotometry. Therefore, the maximum wavelength should not always be chosen. You have also to consider selectivity. In higher wavelengths, less compunds absorbs, improving selectivity. This may be the case.

By changing the solvent with Dibenzothiophene what will be the effect on λ max?
@Satadru Chakrabarty could you please discuss about your solvent which you have used to find λ max of your sample(DBT).
