Red light stop: The experiment uses multiple frequencies of light to cool the CaOH atoms to a fraction of a degree above absolute zero. (Courtesy: John Doyle) Physicists in the US have created ...

After firing the lasers and bombarding the molecules with light, the scientists gathered around the camera to check the results. By seeing how far these cold molecules expanded they would know almost ...

OUR ideas and knowledge of the shapes of polyatomic molecules are largely confined to the ground electronic states. Comparatively little progress has been made in knowledge of the symmetries of ...

THE recent development of our knowledge of the electronic structures of molecules makes it possible to specify with reasonable certainty the particular electron with which a definite molecular ...
