Scientists find new way to detect ortho–para conversion in water

25 agosto 2015

New research has found that water molecules react differently to electric fields, which could provide a new way to study spin isomers at the single-molecule level. Water molecules exist in two forms or ‘isomers’, ortho and para, that have different nuclear spin states. In ortho-water, the nuclear spins are parallel to one another, and in para water, the spins are antiparallel. The conversion of ortho water into para-water and vice-versa is relevant to a broad range of scientific fields from nuclear magnetic resonance (NMR) to astrophysics.
