    Abstract: The adsorption of N2 on Ni(111) at 89–115 K under steady-state (quasiequilibrium) conditions has been studied using Fourier-transform infrared reflection absorption spectroscopy (FT-IRAS) and low-energy electron diffraction (LEED). At very low coverage, a single N 3/4 N absorption band is observed at 2218 cm−1 which is assigned to a singleton N2 adspecies. With increasing N2 pressure, two other bands develop at 2212–2208 and 2204–2203 cm−1, and a faint ( 7/8 × 7/8 )R30° LEED pattern is observed. At even higher pressure, a sharp ( 7/8 × 7/8 )R30° LEED pattern develops together with a relatively broad single band at 2194 cm−1. The enthalpy of adsorption of N2 on Ni(111) is estimated to be −8.4 kcal/mol at zero coverage from isothermal IRAS measurements. Slight attractive interactions between N2 adspecies are detected. The origins of the vibrational features which are related to island formation will be discussed in detail.

    Abstract: A new reflectron time-of-flight mass spectrometer using a pulsed CO2 laser for desorption of neutral molecules, followed by a pulsed, tunable UV laser for resonant multiphoton postionization is described. The innovative features of this instrument are the following: spatially resolved desorption in the μm range, a simple and efficient ion extraction geometry, and several improvements in sample loading, positioning, and observation. Excellent sensitivity in the attomole range and a mass resolution of M/ΔM≊2000 are demonstrated. Primary applications include spatially resolved organic trace analysis and the detection of selected chemical compounds in complex mixtures.
