Hydrogen bonding
molecules to evolve in the test tube. With the discovery of catalytic RNA, and advances in nucleic acid amplification techniques such as the polymerase chain reaction, it became possible to construct laboratory systems that allow the Darwinian evolution of functional RNA (and later DNA) molecules. This is not evolution based on natural selection, but rather directed evolution based on selection...
متن کاملDiscovery of Interstellar Hydrogen Fluoride
We report the first detection of interstellar hydrogen fluoride. Using the Long Wavelength Spectrometer (LWS) of the Infrared Space Observatory (ISO), we have detected the 121.6973 μm J = 2 − 1 line of HF in absorption toward the far-infrared continuum source Sagittarius B2. The detection is statistically significant at the 13σ level. On the basis of our model for the excitation of HF in Sgr B2...
متن کاملHydrogen Bonding in Water
Hydrogen bonding occurs when an atom of hydrogen is attracted by rather strong forces to two atoms instead of only one, so that it may be considered to be acting as a bond between them [99]. Typically hydrogen bonding occurs where the partially positively charged hydrogen atom lies between partially negatively charged oxygen and/or nitrogen atoms, but is also found elsewhere, such as between fl...
متن کاملHydrogen bonding: Attractive arrays.
hydrogen bonding is considered by many to be the ‘master key’ of molecular recognition — owing to its relatively predictable strength and directionality — and plays a major role in the assembly of diverse non-covalent assemblies1. Consequently, the study and exploitation of hydrogen bonds has been central to the development of modern supramolecular chemistry. In particular, numerous applied set...
متن کاملHydrogen bonding between neon and hydrogen fluoride
During the course of our systematic study of water molecule interactions, 1 we recently examined the potential energy surface for the neon atom-water molecule pair. 2 That examination produced an unanticipated feature, namely that a linear hydrogen bond forms, with the neon atom acting as a proton acceptor. By conventional standards,3 that hydrogen bond is weak (0.17 kcal/mole), and would there...
