The analogous reaction with phosphanes ( 1 6) and ( I c)[lbl likewise led stereospecifically to the phosphane oxides ( ) and ( 2 c ) , respectively. The products (2a)-(2c) formed by formal addition of HzO could be characterized on

The pulse recovery method is applied to the triplet states of naphthalene, quinoxalene, and tetramethylpyrazine 03iP) in durene and biphenyi host crystals for 1.25% d Td 4.23%. Temperature dependen~es of the spin-lattice relaxation rates are characteristic of Raman and direct processes.
