High resolution photoelectron spectroscopy of C 60 2
نویسندگان
چکیده
Vibrationally resolved photoelectron spectra of C60 2 are reported at three photon energies: 355, 266, and 193 nm. Complicated vibrational structures were observed for the transition to the C60 ground state with both the Ag and Hg modes being active. An extra feature was observed in the energy gap region between the highest occupied and lowest unoccupied orbitals of C60 in the 266 nm spectra only and it was attributed to an autodetachment process. We also report the most accurate measurement of the electron affinity of C60 ~2.68960.008 eV!. © 1999 American Institute of Physics. @S0021-9606~99!02517-9#

High resolution and low-temperature photoelectron spectroscopy of an oxygen-linked fullerene dimer dianion: C(120)O(2-).
C(120)O comprises two C(60) cages linked by a furan ring and is formed by reactions of C(60)O and C(60). We have produced doubly charged anions of this fullerene dimer (C(120)O(2-)) and studied its electronic structure and stability using photoelectron spectroscopy and theoretical calculations. High resolution and vibrationally resolved photoelectron spectra were obtained at 70 K and at several...
متن کاملAmmonia adsorption and decomposition on the GaAs ( 100 ) - c ( 8 X 2 ) surface
The effect of ammonia exposure and substrate temperature on the reaction of ammonia with GaAs(lOO)-c(8 x 2) has been studied using temperature programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), and high resolution electron energy loss spectroscopy (HREELS). TPD data indicate that thermal decomposition of ammonia occurs at moderate temperatures (250 K). Above 250 K, recombinati...
متن کاملHarmonium: A pulse preserving source of monochromatic extreme ultraviolet (30–110 eV) radiation for ultrafast photoelectron spectroscopy of liquids
A tuneable repetition rate extreme ultraviolet source (Harmonium) for time resolved photoelectron spectroscopy of liquids is presented. High harmonic generation produces 30-110 eV photons, with fluxes ranging from ∼2 × 10(11) photons/s at 36 eV to ∼2 × 10(8) photons/s at 100 eV. Four different gratings in a time-preserving grating monochromator provide either high energy resolution (0.2 eV) or ...
متن کاملThe Synthesis of α-MoO3 by Ethylene Glycol
This study investigated the use of ethylene glycol to form α-MoO₃ (molybdenum trioxide) from ammonium molybdate tetrahydrate at various sintering temperatures for 1 h. During the sintering process, the morphologies of the constituents were observed using scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy was used to explain the reaction process. In this work,...
