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

Accelerating QM/MM Free Energy Computations via Intramolecular Force Matching. [PDF]
J Chem Theory Comput, 2018 The calculation of free energy differences between levels of theory has numerous potential pitfalls. Chief among them is the lack of overlap, i.e., ensembles generated at one level of theory (e.g., "low") not being good approximations of ensembles at the other (e.g., "high"). Numerous strategies have been devised to mitigate this issue.

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

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).

Intramolecular Force Field of Some Tetrahedral Thio and Seleno Anions [PDF]
Zeitschrift für Naturforschung A, 1974 Abstract The orbital valence force field (OVFF) and the Urey- Bradley force field (UBFF) have been employed to evaluate the force constants of thio and seleno anions of VA, VB, VIB and VIIB group atoms of the periodic table. These constants were utilized to examine the relative strength of chemical bonds in isoelectronic sequences ...

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

Vibrational Assignments and Intramolecular Force Field of Trimethylaluminum [PDF]
Bulletin of the Chemical Society of Japan, 1965 Abstract A vacuum infrared cell for reactive or intermediate species has been devised by the use of polyethylene sheets as optical windows. The infrared spectra in the 4000–3100cm−1, 2500–1500 cm−1, 1250–750 cm−1 and 700–65 cm−1 regions can be measured with this liquid cell.
