Abstract

Proton transfer in the hydrogen-bonded systems plays an important role, especially in biological, technological and atmospheric events. The aim of this work is to investigate the change of the proton dynamics along the methanol wires at low temperatures by adding H2O, which has lower proton affinity than methanol, and NH3, which has bigger proton affinity than methanol. In this study, the density functional code of QUICKSTEP package program where the on the fly molecular dynamics calculations performed that is part of the CP2K package program was used. In NH3-containing methanol clusters, the proton is localized on NH3 while in H2O-containing clusters, the proton is delocalized along the methanol wires.

Özet

Hidrojen bağlı sistemlerde proton transferi, özellikle biyolojik, teknolojik ve atmosferik olaylarda önemli rol oynar. Buçalışmanın amacı, düşük sıcaklıklarda metanol zincirlerine proton afinitesi metanol den küçük olan H2O ve metanol denbüyük olan NH3 ilavesi ile proton dinamiğinin metanol zincirleri boyunca değişimini incelemektir. Çalışmada, CP2K paketprogramının bir parçası olan on the fly moleküler dinamik hesaplamaların bulunduğu yoğunluk fonksiyon kodu olanQUICKSTEP paket programı kullanılmıştır. NH3 içeren metanol kümelerinde, proton NH3 üzerine lokalize olurken; sumolekülü içeren kümelerde proton metanol zincirleri boyunca de lokalize olmaktadır.
