Abstract
Water present in the nanoscale confined medium like the hydrophobic interior of the carbon nanotubes (CNT) is known to extol unique properties that depart largely from their behavior in the bulk form. Considering suitable model systems that structurally resemble single unit of the CNT, we demonstrate that two unique parameters namely the local nanoscale curvature and the confinement length are of cardinal importance in governing the structural and electronic properties of water molecule present inside CNT in a general manner. Water molecule encapsulated between the model systems that offer both the above two effects exhibits dramatic trend in the interaction energy with respect to the variation of these parameters. In relation to the curvature of the model system, we propose three different regimes where water molecule experiences a distinct trend in the stabilization energy. Similarly, a confinement distance of 6 Å also marks as a borderline for the distinct manifestations in the stabilization energy of the water molecule. These two parameters also play a key role in governing the significant variations in the structural parameters, Mulliken charges, and red and blue shift in the O–H vibrational frequencies of the encapsulated water molecule. There seems to be interplay between curvature and confinement in deciding the electronic properties of water in the nanoscale confinement.
