A detailed theoretical analysis of the bonding situation in complexes of (NH3)3Ptn with 9-methylguanine and 9-methyladenine has revealed that electrostatics provide a larger contribution to the Pt N7(nucleobase) bond energy... 

Fig. 3.4. Experimental electrostatic potential map for the molecule of 9-methyladenine removed from the lattice. Note the marked difference between the electrostatic potentials around N-H (donor), (acceptor), and C-H (contours 0.05 e A-1) [218]...

Maxam-Gilbert DNA sequencing relies on mcthylation of guanosine and adenosine nitrogens. Use SpartanView to examine electrostatic potential maps of 9-methyl-guanine and 9-methyladenine, and compare the electrostatic potentials at positions 7 on guanine and 3 on adenine. Which molecule is the better nucleophile, and why ... 

Figure L Molecular topology, atomic numbering, and in-plane molecular electrostatic potential energy maps for a, 9-methylguanine (9-MeG) b, 9-methyladenine (9-MeA) c, 1-methylcytosine (1-MeC) and d, the N 1-deprotonated thymine monoanion (Thy ). Contour levels for the electrostatic potential energy maps are given in kcal/mol as in Ref. 21 and 26.
