Hydrogen-Bond Exchange Seen in Real Time
	Hydrogen bond exchange has been observed for the first time by a team of chemists from Kyoto University with the help of a scanning tunneling microscope while monitoring a single water dimer – two molecules of water bonded together. The hydrogen bond exchange takes place between two molecules with a frequency of a few tens of cycles per second, and the new observations may lead to a better understanding of the quantum tunneling and molecul ...
