Intramolecular Force Mapping at Room Temperature. [PDF]
ACS Nano, 2023Acquisition 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.

Accelerating QM/MM Free Energy Computations via Intramolecular Force Matching. [PDF]
J Chem Theory Comput, 2018The 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

Intramolecular Force Contrast and Dynamic Current-Distance Measurements at Room Temperature. [PDF]
Physical Review Letters, 2015Scanning 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 Force Field of some Tetrahedral Molecules and Ions [PDF]
Zeitschrift für Naturforschung A, 1972The 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).

Polymer Mechanochromism from Force-Tuned Excited-State Intramolecular Proton Transfer. [PDF]
Journal of the American Chemical Society, 2022Real-time monitoring of strain/stress in polymers is a big challenge to date. Herein, we for the first time report an ESIPT (excited-state intramolecular proton transfer)-based mechanochromic mechanophore (MM).

Molecular Simulation of Caloric Properties of Fluids Modelled by Force Fields with Intramolecular Contributions: Application to Heat Capacities [PDF]
J. Chem. Phys. 147, 043508 (2016), 2017The calculation of caloric properties such as heat capacity, Joule-Thomson coefficients and the speed of sound by classical force-field-based molecular simulation methodology has received scant attention in the literature, particularly for systems composed of complex molecules whose force fields (FFs) are characterized by a combination of ...

Characterization of Inter- and Intramolecular Interactions of Amyloid Fibrils by AFM-Based Single-Molecule Force Spectroscopy [PDF]
, 2016Amyloids are fibrous protein aggregates defined by shared specific structural features. Abnormal accumulation of amyloid in organs leads to amyloidosis, which results in various neurodegenerative diseases.

Vibrational Assignments and Intramolecular Force Field of Trimethylaluminum [PDF]
Bulletin of the Chemical Society of Japan, 1965A 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 ...
