In this case, reaction of hexahedral silsesquioxane and CF 3 SO 3 H in DMSO conducted in 1 : 12 molar ratio gives heptahedral silsesquioxane. In the first step CF 3 SO 3 H acid attacks siloxane Si-O-Si bonds and the formation of Si-O-SO 2 CF 3 bond parallel with cage opening process is observed and compound B is obtained (Figure below). Such an ...
This convention is grounded in the Leipzig Glossing Rules. [2] Some authors use a lower-case n, for example n H for 'non-human'. [16] Some sources are moving from classical lative (LAT, -L) terminology to 'directional' (DIR), with concommitant changes in the abbreviations. Other authors contrast -lative and -directive.

For all A P H 4 systems in D 4h symmetry, the ground state is a 1g. The exact electronic configuration, however, is dependent on the electronegativity of the main group element. The distortion to tetrahedral geometry has b 2u symmetry. For these A P H 4 systems, the a 2u →b 1g * and e u →e g * one-electron charge-transfer transitions are ...
