“…The distinct bands at 755 and 838 cm À1 result from the in-plane vibrations 1 and 12 of the o-methoxyaniline cation in the D 0 state. The corresponding frequencies of the o-methoxyphenol cation were found to be 756 and 829 cm À1 , respectively [13]. Although the intensity of all other bands in Fig.…”

“…It is known the ionization energy (IE) of o-fluorophenol is 8.67 eV obtained by the mass analyzed threshold ionization spectroscopy [5], the excitation origin energy of S 1 ← S 0 electronic transition of o-fluorophenol is 4.56 eV indicated by REMPI [3], and the S 2 origin is estimated to be 5.79 eV from the UV absorption spectrum [21]. In the present work, we used two ionization schemes to study the ultrafast dynamics of o-fluorophenol.…”

“…Discussions about electronic states of o-fluorophenol are numerous. Examples of such studies include the structural information on the S 0 and S 1 states using hole burning and high resolution ultraviolet spectroscopy [3], excited state hydrogen transfer studied by two-color resonance enhanced multiphoton ionization (REMPI) spectroscopy [4], the observation of the vibrationally resolved cation spectra by mass analyzed threshold ionization spectroscopy [5], nonresonant ionization detected by infrared spectroscopy [6], and vibrational spectra studied by Fourier transforminfrared (FT-IR) and FT-Raman spectroscopy [7,8]. All of these studies rely on the timescale of nanosecond (ns).…”

The ultrafast dynamics of o-fluorophenol via the excited states has been studied by femtosecond time-resolved photoelectron imaging. The photoion and photoelectron spectra taken with a time delay between 267 nm pump laser and 800 nm probe laser provide a longer-lived S 1 electronic state of about ns timescale. In comparison, the spectra obtained by exciting the S 2 state with femtosecond laser pulses at 400 nm and ionizing with pulses at 800 nm suggest that the S 2 state has an ultrashort lifetime about 102 fs and reflects the internal conversion dynamics of the S 2 state to the S 1 state. o-fluorophenol, femtosecond time-resolved photoelectron imaging, excited states PACS: 06.60.

Ever since the introduction of laser technology to the field of mass spectrometry, several disciplines evolved providing solutions to challenging scientific and analytical tasks in research and industry. Among these are techniques involving multiphoton ionization such as Resonance‐Enhanced Multiphoton Ionization (REMPI, R2PI) and Mass‐Analyzed Threshold Ionization (MATI) spectroscopy, a variant of Zero Kinetic Energy (ZEKE) spectroscopy, that possess the ability to selectively ionize certain preselected compounds out of complex mixtures, for example, environmental matrices, with a high level of efficiency. Another key feature of multiphoton ionization techniques is the ability to control the degree of fragmentation, whereas soft ionization is most highly appreciated in most applications. In cases where rich fragmentation patterns are desired for diagnostic purposes, Photodissociation mass spectrometry (PD‐MS) is applied successfully. PD‐MS allows for the cleavage of selected chemical bonds. With the introduction of chromophoric labels in PD‐MS, it became possible to target certain molecules or groups within a molecule. In this review article, an overview of the basic principles and experimental requirements of REMPI and MATI spectroscopy and PD mass spectrometry are given. By means of selected examples, the latest developments and application possibilities in this field over the past decade with special focus on the German research landscape are pointed out. © 2018 Wiley Periodicals, Inc.
