The effect of bonding on the fragmentation of small systems

Recent dissociative recombination (DR) experiments have reported that the observed reaction products depend on the structure, bonding, and charge centre of the molecular ion. For examples, the dominant product channel observed in the DR of D+5 (2), N2O + 2 (1), and D5O + 2 (3) suggests that the former two ions have the form D+3 ·D2, and NO + ·NO (1), respectively, whilst the latter is known to have the form D2O·D + ·D2O (3). Here we compare and contrast these observations by investigating the DR of one of the simplest such systems, Li·H2. This system, a weakly bound cluster with the charge centre located on the lithium atom, will provide us with an excellent opportunity for investigating the role played by the type of bonds and charge centre in the DR process. https://ntrs.nasa.gov/search.jsp?R=20060052469 2017-08-15T05:57:22+00:00Z
