Анотація

У цьому дослiдженнi для вивчення спектрального прояву взаємодiї мiж амiлацетатом (AmAc) та хлороформом було використано теорiю функцiонала густини (DFT) та раманiвську спектроскопiю. Червоний зсув у смузi валентних коливань C=O спостерiгався при зменшеннi концентрацiї AmAc у розчинi, що свiдчить про утворення мiжмолекулярних водневих зв’язкiв у цьому розчинi. На рiвнi DFT/B3LYP/6-311++G(d,p) було визначено оптимальну геометрiю комплексiв, що складаються з мономера AmAc, димера AmAc та хлороформа. Для збору iнформацiї щодо iснування та характеристик водневих зв’язкiв (таких як C–H···O) було використано методи топологiчного аналiзу AIM, RDG, NCI, ELF та LOL. Важлива iнформацiя про мiжмолекулярнi взаємодiї в розчинi була отримана завдяки вiдкриттю зв’язку мiж валентними коливальними смугами C=O та утворенням молекулярних кластерiв.
