A study of the molar absorptivity and structure of vitamin B2 relationship

Molar absorptivity (epsilon) and E(1%, 1 cm) values have been obtained at different pH of the medium containing vitamin B-2 in the solution, s-values ranged from 12000-26000 when the measurement was made at 265 nm at different pH. E(1%, 1 cm) values ranged from 323-710, increasing from lower to higher values as the pH of the medium was changed from 2.6-7.8.
