Figure 11.5—Comparative diagram showing the most common transitions in simple oxygen or nitrogen-containing compounds. These four types of transitions are often shown on a single energy diagram to indicate their relative position, or to indicate the spectral regions involved.

The simplest sulfur ylids are formed from sulfonium salts 69 by deprotonation in base. These ylids react with carbonyl compounds to give epoxides.18 Nucleophilic attack on the carbonyl group 70 is followed by elimination 71 of dimethylsulfide 72 and formation of the epoxide 73. You should compare diagram 71 with diagram 23 in chapter 15. The phosphonium ylid reacted by formation of a P-0 bond and an alkene in the Wittig reaction. The sulfonium compound reacts by formation of a C-O bond 71 as the S-O bond is much weaker than the P-0 bond. The sulfonium salt 69 can be reformed by reaction of 72 with Mel.

The CEO is an operator in contrast to the GF, which is a function. In Fig. 6, we compare diagrams for single-photon exchange for the standard evolution operator, the GF and the CEO.

Critical potentials for SCC of a metal/solution system can be related to its -pH diagram as these diagrams describe the conditions at which film formation and metal oxidation occur. The potential-pH (fi-pH) diagram of carbon steel shows that SCC is associated with potentials and pH values at which phosphate, carbonate, or magnetite films are stable, while Fe + and HFeOJ are metastable. A comparable diagram exists for a 70 Cu-30 Zn brass in a variety of solutions (96).

This could indicate, in particular, that the greater the concentration [Vci] in the initial material (i.e. the higher o i) the higher the rate of coloration The fact that the rate of coloration suddenly decreases as the temperature is lowered could support this point when the temperature is decreased, the material enters the extrinsic conductivity range where the concentration [Vq] ] rapidly decreases (compare diagram 1 and 5). This point has already been underlined by Tsikin and co-workers In the same way the chemical coloration rate was observed to sharply decrease in the extrinsic conductivity range. ...
