## Abstract NMR and CD data have previously shown the formation of the T~4~ tetraloop hairpin in aqueous solutions, as well as the possibility of the B‐to‐Z transition in its stem in high salt concentration conditions. It has been shown that the stem B‐to‐Z transition in T~4~ hairpins leads to S (s
