Photoelectron spectra of [Formula: see text] cluster anions (3≤n, m≤6) were measured at the photon energy of 3.49 eV, by using a magnetic-bottle electron spectrometer having ~60-meV resolution. The [Formula: see text] clusters were produced by laser vaporization of a carbon–silicon mixture rod in a He carrier gas. The spectra of the [Formula: see text] clusters are similar to those of pure [Formula: see text] clusters in the peak positions and their envelopes, which is attributed to the similarity in electronic structure of Si and C atoms, leading to a similar geometry. In contrast, the similarity in the photoelectron spectra is not observed between [Formula: see text] and [Formula: see text] clusters, which is attributed to a change in their geometry; from chain to ring.

Uv Photoelectron Spectroscopy

The electronic energy and dynamics of solvated electrons, the simplest yet elusive chemical species, is of interest in chemistry, physics, and biology. Here, we present the electron binding energy distributions of solvated electrons in liquid water, methanol, and ethanol accurately measured using extreme ultraviolet (EUV) photoelectron spectroscopy of liquids with a single-order high harmonic. The distributions are Gaussian in all cases. Using the EUV and UV photoelectron spectra of solvated electrons, we succeeded in retrieving sharp electron kinetic energy distributions from the spectra broadened and energy shifted by inelastic scattering in liquids, overcoming an obstacle in ultrafast UV photoelectron spectroscopy of liquids. The method is demonstrated for the benchmark systems of charge transfer to solvent reaction and ultrafast internal conversion of hydrated electron from the first excited state.

Two Peaks

Photoelectron spectra of [Formula: see text] (M= Al , Cu, Ag, and Au) cluster anions were measured at the photon energies of 3.49 and 4.66 eV using a magnetic-bottle electron spectrometer having ~60-meV resolution. The electron affinities of AlS−, CuS−, AgS−, and AuS− are 2.60(3), 2.10(3), 2.09(3), and 2.44(3) eV, respectively. The large EA of AlS− is attributed to large stability by six bonding electrons, and a new electronic state of A ′ 2Π can be found 0.4 eV above the AlS ground state, which is in agreement with a theoretical calculation. In the photoelectron spectrum of AuS−, two peaks due to a splitting by the L–S coupling could be observed, and the amount of the splitting is 0.18(2) eV. The results of aluminum clusters containing sulfur atom will also be presented.

Theoretical Results

Photoelectron spectra of annealed carbon-cluster anions [Formula: see text]n=5–70, are presented which show vibrational fine structure. From the vibrational frequencies, theoretical results, and ion mobility measurements, the geometry of the clusters can be determined: clusters with n=5, 7, and 9 are linear chains; n=10, 12, 14, 16, and 18 build monocyclic rings; for n=20, 24, and 28 the vibrational features correspond best to bicyclic rings; and for even n>30 fullerenes are found. In contrast to carbon, the mass distribution of silicon-cluster anions (up to n≈30) does not change dramatically upon annealing. An enhanced abundance of typical fragmentation products [Formula: see text] with n=4, 6, 7, and 10 is found. The vibrational fine structure for [Formula: see text] agrees with that of a pentagonal bipyramid.

Excess Electrons

Experimental studies of the electronic structure of excess electrons in liquids—archetypal quantum solutes—have been largely restricted to very dilute electron concentrations. We overcame this limitation by applying soft x-ray photoelectron spectroscopy to characterize excess electrons originating from steadily increasing amounts of alkali metals dissolved in refrigerated liquid ammonia microjets. As concentration rises, a narrow peak at ~2 electron volts, corresponding to vertical photodetachment of localized solvated electrons and dielectrons, transforms continuously into a band with a sharp Fermi edge accompanied by a plasmon peak, characteristic of delocalized metallic electrons. Through our experimental approach combined with ab initio calculations of localized electrons and dielectrons, we obtain a clear picture of the energetics and density of states of the ammoniated electrons over the gradual transition from dilute blue electrolytes to concentrated bronze metallic solutions.
