Entropic Effects on Hydrated Alkali-Metal Cations: Infrared Spectroscopy and ab Initio Calculations of M+(H2O)x=2−5 Cluster Ions for M = Li, Na, K, and Cs

Abstract: A delicate balance between competing and cooperating noncovalent interactions determines the three-dimensional structure of hydrated alkali-metal ion clusters. A critical factor influencing the balance reached is the internal energy content (or effective temperature) of the ion cluster. Cold cluster ions (approximately 50-150 K) have little internal energy, and enthalpic contributions have a greater influence on the relative population of low-lying minima. In clusters whose internal energy distributions corres… Show more

“…The relatively large separation in free energy supports the assignments of R3c and R3d as major and minor contributors, respectively. In similar M + (H 2 O) 3 (M = Li, Na, K) experiments, an isomer comparable to R3c has been assigned as the only contributor [10]. For the case of M = Cs, small contributions from the isomers analogous to R3a, R3b and R3d were also observed.…”
