About the Cover:

This month's cover features models of two molecules commonly used in sunscreens: p-methoxycinnamate and oxybenzone. Also shown are the ultraviolet spectra of these two molecules. The photochemistry of sunscreens is discussed by Kimbrough (page 51) and an experiment on the spectrophotometric analysis of sunscreens is explored by Cornelius and co-workers (page 99).
