Similar bonds likely exist in pure water, they wrote, when a hydrogen atom finds itself sandwiched between two water molecules. But those bonds are believed to exist but not be as long-lived ...

While water stands apart with its unique polar properties, hydrogen bonds can form between ... of the two peptide units. "All of the internal vibrations of hydrogen bonded molecules that we ...

Hydrogen bonds are typically thought of as weak ... in which the hydrogen ion is equally shared between the two water molecules. The new results echo the Zundel ion’s behavior, says chemist ...

What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic attraction between an atom and the positive ...
