Intramolecular Force Fields and Vibrational Amplitudes of Disulfur Monoxide Isotopes
Spectroscopy Letters, 1977Abstract The force constants of S2O have been calculated smploying GVFF and UBFF models. The reliability of the set of force constants have been examined. The mean amplitudes of vibration have also been evaluated at three temperatures, viz., 0°K, 298·15°K and 500°K. The results have been briefly discussed.

Inspired by donor-acceptor (D-A) polymers in organic solar cell and the extended conjugation effect, a conceptual design of D-π-A-type mesoporous carbon nitride with benzene or thiophene as a π-spacer is proposed as an efficient photocatalyst for ...

On the Effects of Intramolecular van der Waals Forces
The Journal of Chemical Physics, 1960Evidence for the existence of strong nonbonded repulsions between atoms bonded to a given atom is cited. It is observed that bond angles in ethylene derivatives and related molecules can be correlated with a simple ``hard sphere'' model in which atomic positions are presumed to be governed by the sizes of spherical atoms packed around a given atom ...

Characterization of Intermolecular and Intramolecular Interactions with the Atomic Force Microscope
2014The atomic force microscope (AFM) is a powerful nanoscale instrument that is capable of simultaneously imaging biomolecules and measuring the forces between biomolecules attached to the probe and the surface. In this review, we provide an introduction to the experimental and theoretical considerations that are involved in studying single molecular ...

Large molecules on surfaces: deposition and intramolecular STM manipulation by directional forces
Journal of Physics: Condensed Matter, 2010Intramolecular manipulation of single molecules on a surface with a scanning tunnelling microscope enables the controlled modification of their structure and, consequently, their physical and chemical properties. This review presents examples of intramolecular manipulation experiments with rather large molecules, driven by directional, i.e. chemical or

Self‐Assembly of an Unlikely Occurring Quadrangular Tube by Modulating Intramolecular Forces
Angewandte ChemieAbstractOne of the central focuses in self‐assembly is precisely controlling the self‐assembly pathway so that the target molecules can be produced exclusively. Trans‐1,2‐cyclohexanediamine contains two amino units that form a 60° angle when projected on a plane.

The structure of intramolecular triplex DNA: atomic force microscopy study.
Journal of molecular biology, 2002We applied atomic force microscopy (AFM) for direct imaging of intramolecular triplexes (H-DNA) formed by mirror-repeated purine-pyrimidine repeats and stabilized by negative DNA supercoiling. H-DNA appears in atomic force microscopy images as a clear protrusion with a different thickness than DNA duplex.
