We exploited recent advances in isomer-specific cluster vibrational spectroscopy to explore the fundamental relation between the hydrogen (H)-bonding arrangement of a set of ion-solvating water molecules and the chemical activity of this ensemble. We find that the extent to which the nitrosonium ion (NO+) and water form nitrous acid (HONO) and a hydrated proton cluster in the critical trihydrate depends sensitively on the geometrical arrangement of the water molecules in the network. Theoretical analysis of these data details the role of the water network in promoting charge derealization. date: 2010-01-15 date_type: published publication: Science volume: 327 number: 5963 pagerange: 308 - 312 refereed: TRUE issn: 0036-8075 id_number: 10.1126/science.1177118 pmid: 20075247 citation: Relph, RA and Guaseo, TL and Elliott, BM and Kamrath, MZ and McCoy, AB and Steele, RP and Schofield, DP and Jordan, KD and Viggiano, AA and Ferguson, EE and Johnson, MA (2010) How the shape of an H-Bonded network controls proton-coupled water activation in HONO formation.
