Are there hydrogen bonds in supercritical methanol and ethanol?
Article Abstract:
Ethanol and methanol are likely substitutes of water as supercritical solvents. Scientific investigations examining the chemical shift and hydrogen bonding in methanol and ethanol were reviewed. Nuclear magnetic resonance spectroscopy, X-ray diffraction, infrared spectroscopy and other analytical techniques were utilized. The chemical structure of the alcohols upon dilution in an inert solvent were further analyzed. The findings demonstrate that temperature and pressure influence the chemical shift in both alcohols.

Temperature and length scale dependence of tetraalkylammonium ion-amide interaction
Article Abstract:
The temperature and length scale dependence of tetraalkylammonium salt-amide interaction in water are investigated. The interaction increases with an increase in cation size till a maximum is reached, after which the reverse trend is observed, as water is unable to maintains its H-bond network around the large tetraalkylammonium cation.

Isomers of the uracil dimmer: An ab initio benchmark study
Article Abstract:
The intermolecular binding energies [D.sub.e] of the ten doubly hydrogen bonded [uracil.sub.2] isomers are investigated by the correlated resolution of identity MP2 (RMIP2) method. All structures are optimized at the RIMP2/aug-cc-pVTZ level.
