At 25 °C, 99.99% of all molecules in a cyclohexane solution adopt this conformation. Collisional energy transfer in the bimolecular region. H distance measurement in ultrafast magic angle spinning solid state NMR spectroscopy. Maleimide groups are stable for 64 hours in 0.1 M sodium phosphate buffer, pH 7 at 4°C. "Reproduced from" can be substituted with "Adapted from". Bob Grünberg, Thomas Emmler, Egbert Gedat, Ilja Shenderovich, Gerhard H. Findenegg, Hans-Heinrich Limbach, Gerd Buntkowsky. The optical pumping phenomenon exists only at ultralow temperatures. to reproduce figures, diagrams etc. The high-temperature phase I, stable between 186 K and the melting point 280 K, is a plastic crystal, which means the molecules retain some rotational degree of freedom.

Influence of Humidity on Electrical Characteristics of Self-Assembled Porous Silica Low-k Films. Bromine and iodine substituents β to a methine proton produce an enhanced SCS, which increases with the number of attached carbons, i.e. Please note: If you switch to a different device, you may be asked to login again with only your ACS ID.

Cryoprotection of lipid membranes for high-resolution solid-state NMR studies of membrane peptides and proteins at low temperature. Progress in Nuclear Magnetic Resonance Spectroscopy. This conformation can be derived from the boat conformation by applying a slight twist to the molecule so as to remove eclipsing of two pairs of methylene groups. In studies of biomolecular systems, low-temperature NMR has several motivations. Two examples from my laboratory are studies of molecular rotation and orientational ordering in solid C60 at low temperatures and studies of unusual electronic states, called skyrmions, in two-dimensionally confined electron systems within semiconductor quantum wells. If you are the author of this article you do not need to formally request permission NMR Study of Water-Filled Pores in One of the Most Widely Used Polymeric Material:  The Paper.

He had several attempts at publishing these ideas, but none succeeded in capturing the imagination of chemists. Their relative stabilities are: chair > twist boat > boat > half-chair. NMR sensitivity generally increases with decreasing sample temperature. Marco Fragai, Claudio Luchinat, Giacomo Parigi, Enrico Ravera.
