Carbon-doped In Ga As structures have been grown on InP by metalorganic molecular beam epitaxy using carbontetrabromide as the dopant source. Hall, secondary ion mass spectrometry (SIMS) and X-ray measurements were done to characterize the material. Doping levels from 2 脳 10 to 7 脳 10 cm...

To illustrate, consider the interaction of the pz orbitals in a row of carbon atoms as the number of carbon sites N varies from small to very large (Figure 2).37 For N = 2, bonding and antibonding combinations are split by 2HBB (often denoted as β, the resonance integral)...
The high aromaticity (fa) of up to 95.9% suggests the aromatic nature of the majority of carbon atoms. The molar percent of aromatic bridgehead carbon (xb), an indicator for aromatic cluster size45, was estimated to be 0.36, in between the value of phenanthrene (0.286) and pyrene (0.375...
The density was mea- sured by the flotation method with a carbon tetrachloride-ethylene bromide mixture as me- dium at 30°C. FORMATION OF THREE MODIFICATIONS The conditions of formation and mutual transi- tion of form I, II, and III are shown in Figure 1. All the transitions observed ...
The other starts with rate determining heterolysis of the benzylic carbon-bromine bond and finally leads to a mixture of E- and Z isomers in the thermodynamic ratio, with the E-bromostyrene strongly predo- minating. In the presence of % the latter pathway is suppressed completely, while the...
Click on the diagram to display the various bonding and antibonding molecular orbitals. The molecular orbital diagram for the π-molecular orbitals of acrolein shows the perturbation of the conjugated system from that of butadiene and the large lobe of the beta carbon in the LUMO. 502 () ...

and separation of aromatics of different carbon numbers, for example, mixtures of benzene, toluene, and mixed C8aromatics; separation of aromatic compounds from aliphatic compounds, especially aromatic molecules with from 6 to 8 carbon atoms from C5to C10(naphtha range) aliphatics; separation of ole...
