Abstract:
All-atom molecular dynamics simulations have been employed to study deep eutectic solvents (DESs) consisting of thymol or naphthol as hydrogen bond donor (HBD) and menthol as hydrogen bond acceptor (HBA). Radial and spatial distribution functions demonstrate the presence of specific interactions between the components in both systems. The highest percentage of strong H-bond was found in the pair having the phenolic systems as HBD and menthol as HBA. The number of hydrogen bonds formed between various components decreases with an increase in temperature. Self diffusivity of the non-ionic DESs is higher than that of ionic DESs. Liquid - vapor interfaces of all the systems are enriched with HBAs.

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Chemical Shift: Internal References and Solvent Effects
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
