ESCA applied to liquids. ESCA spectra from molecular ions in solution
Chemical Physics Letters, 1976Abstract The application of ESCA to solutions of molecular ions is described. As an example is chosen the N-methyl-glucamine salt of 5-[ p -(2-pyridylsulfamoyl)phenylazo] salicylic acid. It is shown that by exchange of one of the ions in the solution the ESCA spectra of the individual ionic components may be deduced.

Phosphorus and Sulfur and the Related Elements, 1983
Abstract The nature of the P[dbnd]P bond in E-bis(2,4,6-tri-tert-butylphenyl)diphosphene was studied by means of ESCA, indicating that the phosphorus 2p binding energy is the lowest among those for common organophosphorus compounds.

ESCA for microelectronic applications
Proceedings, annual meeting, Electron Microscopy Society of America, 1983As the dimensions of microelectronic devices continue to shrink, the use of surface sensitive analysis techniques to characterize thin film structures continues to grow. These techniques including: ESCA or XPS (X-ray photoelectron spectroscopy), AES (Auger electron spectroscopy), SIMS (secondary ion mass spectroscopy) and ISS (ion scattering ...

ESCA‐Untersuchungen an Prussiaten
Zeitschrift für anorganische und allgemeine Chemie, 1977AbstractMittels der Röntgen‐Photoelektronenspektroskopie wurden an Prussiaten die Ionisierungsenergien bestimmt. Die Ergebnisse werden als Folge der σ–π‐Wechselwirkungen interpretiert. Es wird ferner gezeigt, daß Ladungsausgleich zwischen Zentralatom und Liganden durch die Anzahl der möglichen π‐Bindungen bestimmt wird.

ESCA applied to liquids IV. A wire system for ESCA measurements on liquids
Journal of Electron Spectroscopy and Related Phenomena, 1975Abstract A wire system for ESCA investigations of liquids is described. It uses a thin wire which is continuously coated with liquid and moved past the entrance The study of liquids with ESCA has great potential and already the first results obtained so far are quite promising.

Electron spectroscopy for chemical analysis (ESCA) is perhaps the most valuable single technique available for the analysis of the surfaces of materials intended for biomedical studies. This paper will consider why surface analysis is important for these systems, why ESCA can be used to obtain information of value and how ESCA has been applied to ...

This paper describes two observations made on CaF2 during electron spectroscopy for chemical analysis (ESCA) studies. The first observation is that an ion-etched CaF2 surface adsorbs several layers of water even in an ultrahigh vacuum (UHV) chamber (P ∼ 2×10-10 torr).

OSA Annual Meeting, 1993
This paper, being a presentation of laboratory imaging ESCA instrumentation, will begin with a brief historical review of the various methods that have been used in the past to generate X-ray induced photoelectron images of surfaces using fairly standard laboratory ESCA equipment.

Electron Spectroscopy for Chemical Analysis (or Applications) — ESCA — is based on the following principle1, 2): monochromatic short-wavelength radiation is used in order to detach electrons from the sample, the kinetic energy of the electrons being measured by means of an electron analyser.
