Intramolecular Force Mapping at Room Temperature. [PDF]
ACS Nano, 2023 Acquisition of dense, three-dimensional, force fields with intramolecular resolution via noncontact atomic force microscopy (NC-AFM) has yielded enormous progress in our ability to characterize molecular and two-dimensional materials at the atomic scale. To date, intramolecular force mapping has been performed exclusively at cryogenic temperatures, due

Intramolecular Force Field of some Tetrahedral Molecules and Ions [PDF]
Zeitschrift für Naturforschung A, 1972 Abstract The orbital valence force field (OVFF), and the Urey-Bradley force field (UBFF) have been employed to calculate the force constants for six molecules and ions (AlCl4 -, AlBr4 -, AlI4 -, Til4 - , Os16O4 , and Os18O4).

The Interplay of Inter- and Intramolecular Hydrogen Bonding in Ether Alcohols Related to n-Octanol [PDF]
Moleculesn-Octanol and related ether alcohols are studied via molecular dynamics (MD) simulations using the two classical all-atom force fields OPLS-AA and CHARMM. The ether alcohols studied possess one ether functionality separated by varying n carbon atoms from

Intramolecular Force Contrast and Dynamic Current-Distance Measurements at Room Temperature [PDF]
Physical Review Letters, 2015 Scanning probe microscopy can be used to probe the internal atomic structure of flat organic molecules. This technique requires an unreactive tip and has, until now, been demonstrated only at liquid helium and liquid nitrogen temperatures. We demonstrate intramolecular and intermolecular force contrast at room temperature on PTCDA molecules adsorbed on

Analysis of two intramolecular proton transfer processes in terms of the reaction force
The Journal of Chemical Physics, 2004 The negative derivative of the potential energy along an intrinsic reaction coordinate defines a force that has qualitatively a universal form for any process having an energy barrier: it passes through a negative minimum before the transition state, at which it is zero, followed by a positive maximum.

Q-model of electrode reactions: altering force constants of intramolecular vibrations
Physical Chemistry Chemical Physics, 2018 Vibrational force constants of molecules can be altered in electrode reactions. A theory is formulated accounting for such effects in terms of non-parabolic free energy surfaces.
