Physical phenomena other than rates and equilibrium constants can be correlated by Hammett-type relationships. For example, as Figure 2.4 shows, in 13C nuclear magnetic resonance spectroscopy (called Cmr) the chemical shift of the cationic carbon in 17 is correlated by Brown s cr + values.21 And the C=0...

The fatty acid composition of olive oil ranges from 7.5-20% palmitic acid, 0.5-5% stearic acid, 0.3-3.5% palmitoleic acid, 55-85% oleic acid, 7.5-20% linoleic acid, and 0.0-1.5% linolenic acid. Myristic, heptadecanoic and eicosanoic acids are found only in trace amounts (Table 9.1). Recently, Scano and co-workers (1999), using 13C nuclear magnetic resonance spectroscopy, detected and quantified c/.v-vaccenic (11-18 1) and eicosenoic acids.
