Some scientists look to the outer reaches of the universe to find new knowledge. For William Hase, a chemistry researcher at Texas Tech University, essential questions remain closer to home: in the chemical bonds, and molecule and surface collisions that occur all around us.
While classical notions of chemical reactions may hold for some molecules, mounting evidence shows that everyday reactions are more complicated than previously thought. Different kinds of energies - vibrational, rotational and translational - may be required to activate a reaction. Moreover, the rupture and formation of bonds during chemical reactions involve electron-electron and electron-nuclei interactions, which complicate matters.
