We report the detection of absorption lines by the reactive ions OH+, H 2 O+ and H 3 O+
along the line of sight to the submillimeter continuum source G10. 6–0.4 (W31C). We used …

New high-level ab initio quartic force field (QFF) methods are explored which provide
spectroscopic data for the electronically excited states of the carbon monoxide, water, and …

Observing changes in molecular structure requires atomic-scale Ångstrom and femtosecond
spatio-temporal resolution. We use the Fourier transform (FT) variant of laser-induced …

The threshold photoelectron spectrum of methylene (CH 2), produced by consecutive H
atom abstractions on methane, has been recorded using synchrotron radiation. The …

The line intensity of photoelectron spectra when either the neutral or cationic species display
a Renner-Teller coupling is derived and applied to the modeling of the photoelectron …

By combining electronic structure and scattering calculations, quasidiabatic potential energy
surfaces of both bound Rydberg and electronic resonant states of the water molecule are …

We mapped the global three-dimensional potential energy surface (3D-PES) of the water
cation at the MRCI/aug-cc-pV5Z including the basis set superposition (BSSE) correction …

One of the significant challenges of modern science is to track and image chemical reactions
as they occur. The molecular movies, the precise spatiotemporal tracking of changes in their …

Over recent years electronic spectroscopy has developed significantly, with key applications
in atmospheric chemistry, astrophysics and astrochemistry. High Resolution Electronic …

This paper reports that the absorption spectra of H 2 O+ have been measured by tunable
mid-infrared diode laserspectroscopy in the spectral range of 1100–1380 cm-1. The H 2 O+ …
