Cover Figure


COVER A hydrogen atom (white) colliding with heavy water can replace (upper) a deuterium atom (blue), extract it (lower), or just bounce off. Exciting the water with a laser influences the outcome. Understanding how to influence chemical reactions requires accurate theory for the atomic motion on potential energy surfaces like those represented in yellow here. See page 961.
