Radial distribution functions between urea derivatives. (a) UR-UR RDFs. Red open triangle: NF + UR + Water system, 𝑡=3 ns; black cross: UR + Water system, 𝑡=3 ns; blue line: NF + UR + Water system, 𝑡=0 ns; purple line: UR + Water system, 𝑡=0 ns; (b) MU-MU RDFs. Red open triangle: NF + MU + Water system, 𝑡=3 ns; black cross: MU + Water system, 𝑡=3 ns; blue line: NF + MU + Water system, 𝑡=0 ns; purple line: MU + Water system, 𝑡=0 ns; (c) EU-EU RDFs. Red open triangle: NF + EU + Water system, 𝑡=3 ns; black cross: EU + Water system, 𝑡=3 ns; blue line: NF + EU + Water system, 𝑡=0 ns; purple line: EU + Water system, 𝑡=0 ns; (d) BU-BU RDFs. Red open triangle: NF + BU + Water system, 𝑡=3 ns; black cross: BU + Water system, 𝑡=3 ns; blue line: NF + BU + Water system, 𝑡=0 ns; purple line: BU + Water system, 𝑡=0 ns.
