Drugs often absorb strongly in the UV. As an example, ε(254nm) = 16,000 and ε(267nm) = 19,000 for the antibiotic tetracycline and ε(254nm) = 16,000 and ε(267nm) = 15,000 for the epi-tetracycline, an inactive hydrolysis product. If a mixture of the two exhibits absorbances of 0.402 at 254nm and 0.432 at 267nm, what is the concentration of each compound?
