Table 2.

Stability and configurational energies for five different i-motif structures

i-Motifmodel^∗	Stability^†	Number ofC-H⁺-C pairs	Configurational energy (kcal mol⁻¹)	Observed by NMR (31)
A	1	5	−168	No
B	3	4	294	Yes
C	2	4	241	Yes
D	5	5	531	No
E	4	5	471	No

^∗

i-Motif models correspond to the structures in Fig. 5, A–E.

^†

Stability order is based on calculated configurational energies, with model A the most stable and model D the least stable.
