Physicists Solve a 50-Year Mystery About a Critically Important Molecule
After relying on an educated guess for decades, scientists have finally confirmed the dipole moment of aluminum monochloride (AlCl), an elusive but important molecule known to sneak around the interiors of ancient galaxies. An electric dipole moment is a measure of polarity—a crucial determinant for many physical properties of any system, such as its boiling point or solubility. Given its importance, the new result, published last month in Physical Review A, presents exciting opportunities for
