The δP values (in ppm) collected at 20°C are given for the first and last dinucleotide steps of the four dodecamers and for their internal counterparts. For dinucleotides present in several copies, δP is the average value, with the standard deviations in brackets. The last column reports δPs predicted depending on the dinucleotidic sequence (40).
