Comparison of Magnetic Deflection among Neutral Sodium-Doped Clusters: Na(HO), Na(NH), Na(MeOH), and Na(DME).

Using a pulsed Stern-Gerlach deflection experiment, we present the results of a comparative study on the magnetic properties of neutral sodium-doped solvent clusters Na(Sol) with = 1-4 (Sol: HO, NH, CHOH, CHOCH). Experimental deflection ratios are compared with values calculated from molecular dynamics simulations. NaNH and NaHO are deflected as a spin 1/2 system, consistent with spin transitions occurring on a time scale significantly longer than 100 μs.

Magic Numbers for the Photoelectron Anisotropy in Li-Doped Dimethyl Ether Clusters.

Photoelectron velocity map imaging of Li(CHOCH) clusters (1 ≤ n ≤ 175) is used to search for magic numbers related to the photoelectron anisotropy. Comparison with density functional calculations reveals magic numbers at n = 4, 5, and 6, resulting from the symmetric charge distribution with high s-character of the highest occupied molecular orbital. Since each of these three cluster sizes correspond to the completion of a first coordination shell, they can be considered as "isomeric motifs of the first coordination shell".
