**The cover picture shows** an artist's impression of the formation of a metal nanocluster in a solution containing ions and atoms of two different metals. Nanoclusters are UV/Vis active, and in theory it should be possible to follow the exact kinetics of their formation by UV/Vis spectroscopy. In p
bond of (11 h ) ; comparing this value with the bond indices of 1.507 for ( 1 6 ) and 1.537 for ( 1 7 ) shows that the IR wave number of the C=N stretching vibration of ( 1 1 ) is not necessarily so high as for ( 16) and (17).
Triolein, trilinolein and a mixture of both (1:1) were heated at 180 Β°C for 2, 4, 6, 8 and 10 h in the absence of tocopherols or in the presence of a-tocopherol (500 mg kg Γ1 ), d-tocopherol (500 mg kg Γ1 ) or a mixture of a-, b-, g-and d-tocopherol (200Β±250 mg kg Γ1 each).
