Conclusions
-
1.
The effect was studied of the nature of the substituent on the titanium atom on the mechanism of decomposition of molecular negative ions of compounds TiCl4, (C2H5)2TiCl2, [C5H4Si(CH3 2]2TiCl2, (C5H5)2-Ti(CH3)2, [C5H4Si(CH3)3]2Ti(CH3)2, TiCl Al(i-C4H9)3, and Al(i-C4H9)3. Average lifetimes of molecular negative ions of the indicated compounds were measured.
-
2.
The existence of long-lived molecular negative ions of the studied titanium derivatives showed that all of them, including tetrahalides, have positive affinity for an electron.
