P Correlation

In principle it is possible (with a suitably configured spectrometer) to carry out correlation experiments between any pair of NMR-active nuclei. How- [Pg.50]

We mentioned above that it is possible to carry out carbon-carbon correlation experiments using the 2D INADEQUATE procedure. There, as you may remember from the discussion of one-dimensional INADEQUATE, we have a very difficult problem to solve carbon-13 represents only 1.1% of the total carbon nuclei present in a sample. And in the INADEQUATE experiment we need to detect only those molecules containing two carbon nuclei which couple with one another, i.e. about 10 4 of the nuclei present at the same time we have to get rid of the signal coming from those molecules containing only one carbon-13 (the great majority)  [Pg.50]

as in the H,H correlation, the actual 2D spectrum forms the central square, and the ID phosphorus spectra are depicted above and to one side of the square. There is a diagonal and there are cross peaks. [Pg.50]


P correlation of two inorganic hydrated phosphates, (a) bnishite and (b) a bone, are shown [48]. In both cases two phosphorus sites that completely overlap in the 1D MAS spectrum are clearly visible in the 2D spectrum. [Pg.1497]

As 31P is the only phosphorus isotope, these problems do not arise. Figure 30 shows the result of a 2D P,P correlation carried out for compound 6. [Pg.47]

The Hammett cr—p correlation has proved useful in studying substituent effects of aryl-substituted systems.55 In Section 6.1 we consider applications of this linear free-energy relationship to solvolysis with rearrangement. [Pg.230]

Hammett a-p correlations also point to the influence of polar effects in the abstraction reactions. [Pg.506]

Log P correlated well for six-carbon aromatics and small alcohols and carboxylic acids (in regard to number of carbons). Correlations for two-carbon alkanes were also better than the other descriptors (see Figure 5.15). [Pg.163]

These results are now in terms of correlation functions of P2Ct) and, in the field on cases, of P (t), as in linear dielectric and other response theories. The asymmetry given by the last term of the field on expression reveals the interesting possibility of obtaining both P correlations (from the field off response) and P correlations (from the asymmetry). One easily verifies that Benoit s result is obtained for diffusional reorientations, as then = (l/5)exp(-6D t), -(2/15)exp(-6Dt), and PoP2PlPl(t)> = (2/15)exp(-2D t)7 but this form of dynamics is not assumed in the development End effects of joint correlations Eire included in eqs.13 and 14. [Pg.74]

The solubility data in Table I may be used to test the log P correlations in poly(ethylene-co-vinyl acetate) and polyether-urethanes. The correlations in Equations 19 and 20 are derived by combining this data with the reported (20) water solubilities and octanol-water partition coefficients of the steroids (22-24). [Pg.62]
