The polycondensation of Ti(O-i-C 3 H 7 ) 4 (1) and Ti(O-n-C 4 H 9 ) 4 (2), precursors widely employed in sol-gel processes, has been investigated by electrospray ionization mass spectrometry. By analysis of 10 À6 M methanol solutions of compounds 1 and 2, the same ionic species are detected, proving
UV absorption spectra of i-&H, and i-C,H70Z radicals have been obtained following pulse radiolysis of Hz/&H6 and H&HdOr mixtures at a total pressure of 1 atm at room temperature. The i-C3H7 spectrum shows two absorption maxima with t( 233 nm) =89Of. 130 M-' cm-' and ~(205 nm) =780+ 120 M-' cm-', res
