Publikováno v: Journal of Electron Spectroscopy and Related Phenomena. :377-381

Intrinsic ionic centers in solid Xe were produced by (i) ionization in situ by vacuum ultraviolet (VUV) light and (ii) deposition of ion-containing gas on cooled substrate. Laser-induced fluorescence (LIF) from the samples was studied in the range of

Relaxation and vibrational fluorescence of WO in solid neon

Autor: Jürgen Agreiter, Nicola Caspary, Vladimir E. Bondybey, Martin Lorenz

Publikováno v: Chemical Physics Letters. 291:291-299

Studies of laser-induced fluorescence of tungsten oxides in solid neon at 6 K provide interesting insights into the mechanisms of WO relaxation. The relaxation occurs by interelectronic cascade between the vibrational manifolds of excited electronic

Publikováno v: Molecular Physics. 91:483-493

Triatomic CuCl2 is trapped in solid neon (argon) at 6 K (11 K) and investigated by optical spectroscopy using a Fourier transform spectrometer. With the help of optical absorption and laser induced fluorescence spectroscopy, several electronic transi

Publikováno v: Chemical Physics. 189:315-334

A simple source of transient species combining a self-igniting discharge with a pulsed supersonic expansion recently developed in our laboratory is applied to the study of discharges through acetylene. It is found to produce particularly efficiently

FT-IR studies of optically pumped C3 in rare gas matrices. The vibrational and electronic absorption spectrum of the ã 3Πu state

Autor: Jürgen Agreiter, Alice M. Smith, Vladimir E. Bondybey, Cornelia Engel

Publikováno v: Chemical Physics Letters. 207:531-539

Through a double-resonance technique, the FT-IR absorptions of the lowest-lying triplet state of C 3 have been observed in argon and neon matrices. The long-lived a 3 Π u state is populated by an intersystem crossing from the excited A 1 Π u state.
