The cutoff distance 𝑟 0 was set to 2.5 Å. The values for n and m parameters were set to 6 and 12, respectively. The index value for the value of i is chosen in such a way that the RNA forms a total of 10 hydrogen bonds (9 corresponds to hydrogen bonds between complementary bases formed by three base pairs in the stem region, and the rest is formed by the hydrogen bond in the loop structure.
