Volume 75, Issue 9
Pages 1058-1192
About the Cover:

The cover features a color-coded contour plot from the potential energy surface of a collinear, triatomic system. Superimposed on the plot is an atomic-scale diagram showing several types of collisions of a chlorine atom with a methane molecule. These images are part of this month's Viewpoints paper, Anatomy of Elementary Chemical Reactions, by Alexander and Zare (pages 1105-1118).
