Time-domain ¹H NMR characterization of the liquid phase in greenwood

Keywords: 13C and 1H NMR, Contin program, extractives, maritime pine wood, moisture content, Pinus pinaster, Relaxation Time, time domain in 1H NMR, transversal relaxation time

The time domain of ¹H NMR spectroscopy allows straightforward editing of the T₂ relaxation profiles in maritime pine wood. A new method from the Carr-Purcell-Meiboom-Gill sequence is proposed to measure the amount and distribution of water in wood, as well as the location of major dissolved organic materials. A general calibration model giving reliable and precise identification of these parameters is described. The method presented for editing T₂ relaxation profiles (obtained by the Contin program) may be helpful in solving practical drying and gluing problems in the wood industry. It can be used for monitoring chemical modifications of wood fibers involved in the design of wood composite materials.
