In the above reactions the magnesium complex is specifically active catalyst. Neither fl,fl-DBF0X/Ph Zn(Cl04)2 3H20 (10) nor fl,fl-DBF0X/Ph Ni(CI04)2 3H2O (10) shows any catalytic activity.

Immobilization of A and B blood group oligosaccharide haptens and preparation of immunoadsorbents with specificity to anti-A and anti-B antibodies has been carried out with the use of poly acrylate-coated PG (WPG-PA) [124]. Prespacered A and B-trisaccharide-fl-aminopropylglycosides were used for the synthesis. WPG-PA (1 g) quantitatively binds both haptens (2 pinole) whereas some other activated affinity supports (for example, CNBr-Sepharose 4B) do not. On the other hand, glycidoxypropyl-silica binds prespacered haptens completely but these materials reveal no specific adsorptivity. 

G(CH3S02 ) is the yield of CH3S02 radicals, AOH- and AH+ are the decrease and increase of the conductivity in basic and acidic solutions respectively, l is the specific conductivity and l(Haq+) and i(OH ) are known to be 315 and 178 fl-1 cm2, respectively. For dimethyl sulfoxide G(RS02 ) was found to be 5.46 comparing this to G(OH) = 6.0 for N20 -saturated aqueous solution leads to the conclusion that 91% of the OH radicals were added to the sulfoxide bond. There is no proof for the fate of the other 9% it is probable that they abstract hydrogen atoms from the methyl groups. 

To complete the discussion of the second-order interaction between tunneling centers, we note that the corresponding contribution to the heat capacity in the leading low T term comes from the ripplon-TLS term and scales as 7 +2 where a is the anomalous exponent of the specific law. Within the approximation adopted in this section, a = 0. However, it is easily seen that the magnitude of the interaction-induced specific heat is down from the two-level system value by a factor of 10(a/ ) ([Pg.188]

In the analysis of complex PAH mixtures obtained from environmental samples, reversed-phase LC-FL typically provides reliable results for only 8-12 major PAHs (Wise et al. 1993a). To increase the number of PAHs determined by LC-FL, a multidimensional LC procedure is used to isolate and enrich specific isomeric PAHs that could not be measured easily in the total PAH fraction because of interferences, low concentrations, and/or low fluorescence sensitivity or selectivity. This multi-dimensional procedure, which has been described previously (Wise et al. 1977 May and Wise 1984 Wise et al. 1993a, 1993b), consists of a normal-phase LC separation of the PAHs based on the number of aromatic carbon atoms in the PAH, thereby providing fractions containing only isomeric PAHs and their alkyl-substituted isomers. These isomeric fractions are then analyzed by reversed-phase LC-FL to separate and quantify the various isomers. 

H-bonds. Such behavior of the Stokes shifts in protic solvents is typical for specific solvent-solute interactions, and has been seen for many solutes phthalimides, FLs, oxazines, and others [1, 2, 4, 50, 51, 72-74].
