133(27):10360-3.
PMID: 21675746
Phase-sensitive vibrational sum-frequency experiments on the water surface, using isotopic mixtures of water and heavy water, have recently been performed. The experiments show a positive feature at low frequency in...

Nature
. 2011 Jun;
474(7350):192-5.
PMID: 21654801
The air-water interface is perhaps the most common liquid interface. It covers more than 70 per cent of the Earth's surface and strongly affects atmospheric, aerosol and environmental chemistry. The...
