Environmentally sensitive: A combination of C-H⋯·anion hydrogen bonding and hyperconjugative charge delocalization explains the sensitivity of the IR spectrum of the tert-butyl cation to its anion (see high-resolution X-ray structure with a CHB11C

The unique nature of H + in water

Autor: Stoyanov, ES, Stoyanova, IV, Reed, CA

Publikováno v: Chemical Science, vol 2, iss 3

The H+(aq) ion in ionized strong aqueous acids is an unexpectedly unique H13O6+ entity, unlike those in gas phase H+(H2O)n clusters or typical crystalline acid hydrates. IR spectroscopy indicates that the core structure has neither C3v H3O+ Eigen-lik

The basicity of unsaturated hydrocarbons as probed by hydrogen-bond- acceptor ability: Bifurcated N-H+⋯μ hydrogen bonding

Autor: Stoyanov, ES, Stoyanova, IV, Reed, CA

Publikováno v: Stoyanov, ES; Stoyanova, IV; & Reed, CA. (2008). The basicity of unsaturated hydrocarbons as probed by hydrogen-bond-acceptor ability: Bifurcated N-H+⋯μ hydrogen bonding. Chemistry-A European Journal, 14(26), 7880-7891. doi: 10.1002/chem.200800337. UC Riverside: Retrieved from: http://www.escholarship.org/uc/item/57g48370

The competitive substitution of the anion (A-) in contact ion pairs of the type [Oct3NH+]B(C6F5V by unsaturated hydrocarbons (L) in accordance with the equilibrium Oct 3NH+ ⋯A- + nL ⇄ [Oct 3NH+-Ln]A- has been studied in CCl4. On the basis of equi

IR spectroscopic properties of H(MeOH)n+ clusters in the liquid phase: Evidence for a proton wire

Autor: Stoyanov, ES, Stoyanova, IV, Reed, CA

Publikováno v: Stoyanov, ES; Stoyanova, IV; & Reed, CA. (2008). IR spectroscopic properties of H(MeOH)n+ clusters in the liquid phase: Evidence for a proton wire. Chemistry-A European Journal, 14(12), 3596-3604. doi: 10.1002/chem.200701746. UC Riverside: Retrieved from: http://www.escholarship.org/uc/item/55t6q724

The long-standing problem of understanding the nature of the "excess proton" in acidified water is simplified by studying the proton in methanol. The 3D network of hydrogen bonds in H(aq)+ is reduced to a ID problem. Infrared spectroscopic characteri
