The state selective photodissociation of acetylene, C2H2/C2D2, was studied in the wavelength range 121.2–132.2 nm by high resolution Rydberg atom time-of-flight measurements on the atomic fragment, H/D. In the wavelength region studied members of a

The technique of H(D) atom photofragment translational spectroscopy has been applied to the photodissociation of CH4(CD4) at 121.6 nm. Contrary to the previous consensus view, we find simple C–H bond fission to be the dominant primary process follo

The strong radiative single photon coupling between two excited states of sodium atoms (3p and 4d) has been studied at high intensities, exceeding 109 W cm-2. These excited states are probed by Raman-like resonant five-photon ionization processes. Us

Singlet gerade Rydberg states of molecular hydrogen

Publikováno v: The Journal of Chemical Physics. 97:908-926

We investigate the singlet gerade Rydberg series with low total angular momentum J=0,1,2 of molecular hydrogen near the ionization threshold. They are excited by starting at selected rotational levels of the B 1Σ+u (v’=0) state. The spectra show R
