Using a simple lowfield NMR system, we monitored water content in a livingtree in a greenhouse over two months. By continuously running thesystem, we observed changes in tree water content on a scale of halfan hour. The data showed a diurnal change in water content consistentboth with previous NMR and biological observations. Neutron imaging experiments showthat our NMR signal is primarily
Pharma/Biotech. There are many useful NMR appliions in biotechnology and pharmaceutical industries. 1 H and multinuclear NMR Spectroscopy (e.g., 13 C, 19 F, 31 P) are essential tools for structural elucidation and drug discovery. Additionally, they can be used for structural confirmation of both known synthetic drugs and natural products with pharmaceutical effects.
