Intermediate to Penning ionization, in which the unexcited reaction partner is ionized by the excited one [reactions (4) and (5)], and associative ionization, in which only one molecular entity is formed, is the process (3), which has been called by Berry rearrangement ionization. ... [Pg.271]

Rathenium.— Takats et al. have extended their n.m.r. work on the [(diene)-Fe(CO)3] and [(olefin)Fe(CO)4] systems described above to include the analogous ruthenium complexes. Generally the same results were found for, and the same theories could be applied to the respective type of complex. Activation energies in the olefin complexes are higher for ruthenium than for iron and this is attributed to an increased metal-i/-olefin-7i interaction in the ruthenium-olefin bond. This, of course, supports the coupled olefin rotation-Berry rearrangement mechanism outlined above. A preliminary report on [(C7H7)(C7H9)Ru3(CO)e] (50) has tentatively... [Pg.374]

Even more complex experiments have been performed on matrix isolated Fe(C0)4, generated by UV photolysis of Fe(C0)5. Isotopic labelling coupled with CW-CO laser pumping (65) of the CO stretching vibrations ( 1900 cnrl) showed that the rearrangement mode of Fe(C0)4 follows an inverse Berry pseudo-rotation as shown in Figure 8. [Pg.50]
