Abstract:

This dataset includes stable oxygen isotope composition of oil and oil residues (δ18O, per mil), isotope effects of photochemical oxygen consumption (epsilon, per mil), and infrared stretching of oxygen functional groups (%). This dataset supports the publication: Ward, C. P., Sharpless, C. M., Valentine, D. L., Aeppli, C., Sutherland, K. M., Wankel, S. D., & Reddy, C. M. (2019).
