摘要:
我们研究了碳纳米管中氨分子的单链结构。为此,我们采用了 i) 分子动力学模拟(结合量子化学获取的氨氮与氢电荷)和 ii) 格子模型计算 [M.~Druchok 等, J. Chem. Phys. {\f 158}, 104304 (2023)]。研究结果表明,在低于 $100$~K 的中等温度下,氨偶极子出现取向准序,且平行于管轴。
英文摘要:
We examine a single-file chain of ammonia molecules in a carbon nanotube. To this end, we use i) molecular dynamics simulations (combined with the charges for ammonia nitrogen and hydrogen obtained from quantum chemistry) and ii) lattice-model calculations [M.~Druchok {\it et al.}, J. Chem. Phys. {\bf 158}, 104304 (2023)]. Our findings demonstrate the occurrence of the orientational quasiorder of the ammonia dipoles, which become parallel to the tube axis, at intermediate temperatures below $100$~K.
