Fig. 7.23 shows the quantitative r sequence that measures the same rcNH CH cross-correlated relaxation rate as the sequence of Fig. 7.20. Again N-C DQ/ZQ coherence is excited using an HN(CO)CA experiment. Because of cross-correlated relaxation, N-C DQ/ ZQ coherence evolves as described in Eq. (7) ...

Figure 4.24 shows a decrease in for acetylacetone with increasing number of methyl groups in the substituted benzene solvent. Since acetylacetone is more soluble in aromatics than in aliphatics, as illustrated by the K r sequence ...

Attack on either of the equivalent carbon atoms in the oxonium ion leads to inversion of configuration and gives the required (R)(S) sequence. According to Vandenberg molecular models of the transition state indeed indicate less steric hindrance to the attack of the enantiomer of the same stereochemistry. Obviously, the reaction of the (S)(S) oxonium ion with the (S)(S) monomer leads by the same token to the (S)(R) sequence.

Let us assume that the probability of generating a meso sequence when a new monomer unit is added at the end of a growing chain can be denoted by a single parameter, which we shall call Pjn (and similarly Pr for a racemic sequence). This implies an assumption that the polymer obeys Bernoullian statistics, that is, the probability of forming an m or r sequence is independent of the stereochemical configuration of the chain already formed. It follows of course that Pm + Pr =1. because addition can be only m or r type.

Figure 2.12. Primary structure of the ori sequences and their flanking regions. Regions of ori sequences are indicated by thick lines for GC clusters A, B and C and thin lines for AT stretches p, s, I and r. The positions of GC clusters a in ori 4, p in on 4 and 6, y in ori 4, 6 and 7, and S in on 1 are given r sequences are indicated by heavy line boxes r and r sequences by broken line boxes. Other boxes indicate sequences /a, Ip, /g, rz, the excision. sequences of the repeat units of petites a-l/lR/1/26, a-l/lR/14, a-3/1/33, a-3/1/5, anda-l/IR/Z] and the initiation triplet of the open reading frames of ori 1, 2, 3 and 5.
