“…In all solutions, the onset of electron-hole pair production coincides with the absorption threshold of the pure solvent, E 0 , at (7.0 AE 0.1) eV in the alkanes, and (6.3 AE 0.1) eV in tetramethylsilane [9,22]. This shows that the produced electron-hole pairs relate to the excitation of the solvent, and that direct excitation of the solute is negligible by reason of a strong screening by this solvent [9,23,24].…”

“…In particular, electron-hole pairs have received considerable attention in view of applications in the fields of radiation detectors [6] and radiotherapy dosimetry [7]. All these studies share in common the primary event of initial energy absorption, which involves necessarily molecular superexcited states endowed with large oscillator strengths in the vacuum ultraviolet [8,9]. For the description of the dynamical behaviour of these states, it is fundamental to gather parallel spectroscopic data both on their photoexcitation and photoionisation.…”

“…In our previous Letter [9], we have measured the single-photon absorption cross-sections of liquid cyclohexane, 2,2,4 trimethylpentane and tetramethylsilane. The goal of the present Letter is to complete our information on these liquids by collecting experimental data on their photoionisation yields and effective cross-sections.…”

“…A liquid sample for measurement is drawn into the 2-mm diameter aperture in the IRE probe, and the scaled inner environment is purged and then filled with pure nitrogen or argon gas. A Peltier element (10) is in contact with the probe holder (8) by a heat pipe (11) to control the sample temperature over the range of 5-80°C. As the light source of KV-200, a 30-W deuterium lamp was used and a diffraction grating with 2400 grooves per millimeter and a blazed wavelength of 150 nm were utilized as the spectroscopic elements.…”

“…(1) In 1971, Rudloff et al (9) tried to measure FUV spectra of solids in the region of 36-6 eV (34-207 nm) using synchrotron radiation from an electron storage ring. Jung and Gress (10,11) also used synchrotron radiation to observe transmission FUV spectra in the 115-207 nm (10.8-6.0 eV) region of CH 3 OH and C 2 H 5 OH in liquid phases. Kuo et al (12) measured FUV absorption spectra of CH 3 OH in neat solid and rare gas mixtures.…”

This article outlines recent progress in ultraviolet (UV) spectroscopy in the 140–280 nm region of solid and liquid phases. In this article, we refer to the 120–200 nm region as the far‐UV (FUV) region. The word ‘vacuum UV region’ is not appropriate any more at least for the 120–200 nm region because most of recent spectrometers used in this region do not have the vacuum evaporation system but have the nitrogen gas purged system. FUV spectroscopy is concerned with electronic transitions of a molecule, but the absorptivity is very high in the FUV region, and, therefore, this region has been employed to investigate mainly for the electronic states and structure of gas molecules. To observe spectra of solid samples in the FUV region, reflection spectroscopy has been used. However, for liquid samples, in general, it is very difficult to use either absorption spectroscopy or reflection spectroscopy. Accordingly, FUV spectroscopy for liquid samples has almost been an undeveloped research area. To solve these difficulties in FUV spectroscopy we have recently developed a totally new FUV spectrometer based on the attenuated total reflection (ATR) technique that enables us to measure spectra of liquid and solid samples in the 140–280 nm region. This spectrometer has opened up a new era of FUV spectroscopy. This article consists of seven parts: (i) introduction to FUV spectroscopy, (ii) characteristics and advantages of FUV spectroscopy for the study of liquids and solids, (iii) development of new FUV spectrometers, (iv) FUV studies of liquid water and aqueous solutions, (v) FUV spectra of organic molecules in the liquid states, (vi) potential applications of FUV spectroscopy in liquid and solid states, and (vii) time‐resolved (TR) FUV spectroscopy. This article demonstrates that FUV holds considerable promise not only in basic science but also in applications such as qualitative and quantitative analyses, on‐line monitoring, environmental geochemical analysis, and surface analysis.

This article outlines the recent progress in ultraviolet ( UV ) spectroscopy in the 140–280 nm region of solid and liquid phases. In this article, we refer to the 120–200 nm region as the far ultraviolet ( FUV ) region. The word ‘vacuum UV region’ is not appropriate any more at least for the 120–200 nm region because a vacuum evaporation system is not always required, but a nitrogen gas‐purged system is often sufficient. FUV spectroscopy is concerned with electronic transitions of a molecule, but the absorptivity is very high in the FUV region, and therefore, this region has been employed to investigate mainly for the electronic states and structure of gas molecules. To observe the spectra of solid samples in the FUV region, reflection spectroscopy has been used.

This article demonstrates that FUV holds considerable promise not only in basic science but also in applications such as qualitative and quantitative analyses, online monitoring, environmental geochemical analysis, and surface analysis.
