Discovery 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 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...
متن کاملHydrogen fluoride--the protoplasmic poison.
HF is a corrosive mineral acid. It has extremely harmful systemic effects through any route of exposure. In dilute solutions the onset of symptoms is latent. It is important for caregivers to remember that HF has distinct clinical signs and a specific antidote, namely calcium gluconate. The industrial use of HF heightens the importance of being prepared for possible exposures. The emergency med...
متن کاملDiffusion of hydrogen fluoride in solid parahydrogen.
We studied diffusion of hydrogen fluoride (HF) in solid parahydrogen (pH2) around 4 K. Diffusion rates were determined from time dependence of FT-IR spectra of HF monomers. The absorption of HF monomers shows temporal decay due to dimerization reaction via diffusion. It was found that the rates are affected by the sample temperature, the initial HF concentration, and annealing of samples. The o...
متن کاملOn the structure of liquid hydrogen fluoride.
The liquid state is the most complex phase of matter. Densities of liquids are comparable to densities of the solids, implying that the forces between particles in the liquid are of the samemagnitude as those forces present in the solid. However, there is no simplification due to the presence of a lattice and no satisfactory analytic theory of the liquid state exists. However, despite this comp...
