Raman and IR spectroscopy ofGeOn,withn=1,2,3,4,isolated in solid Ar were used for the elucidation of the corresponding molecular structures. The experiments were complemented by extensiveab initiocalculations at different theoretical levels, in the case ofGe2O2additionally by normal-coordinate analys...

In this study, in situ homospectral two-dimensional spectroscopy was used to evaluate catalytic combustion of n-nonane over a plasma-deposited cobalt oxide structured catalyst. This step allows the intermediates created on the catalyst surface during the reaction to be followed. Two conditions were ...
