Intramolecular screening of intermolecular forces

The Journal of Chemical Physics, 1993
By use of nonlocal polarizability densities, we analyze the intramolecular screening of intermolecular fields. For two interacting molecules A and B with weak or negligible charge overlap, we show that the reaction field and the field due to the unperturbed charge distribution of the neighboring molecule are screened identically via the Sternheimer ...

Intramolecular force-compensated hydrogel-based sensors with reduced response times

TM. Technisches Messen, 2019
The method of intramolecular force compensation forms a new approach for reducing the response time of hydrogel-based chemical sensors and improving their long-term stability.

Joyce and Ulysses: integrated and user-friendly tools for the parameterization of intramolecular force fields from quantum mechanical data.

Physical Chemistry, Chemical Physics - PCCP, 2013
The Joyce program is augmented with several new features, including the user friendly Ulysses GUI, the possibility of complete excited state parameterization and a more flexible treatment of the force field electrostatic terms.

Quantization of Molecules, Inter- and Intramolecular Forces

Physical Review, 1943
In diatomic molecules (e.g., ${\mathrm{P}}_{2}$) the distinction is made between the quantization of the electrons of the atomic cores (${\mathrm{P}}^{5+}$), which is assumed to be the same (${1}^{2}$${2}^{8}$) as in the free atom (P), and of the valence electrons ${3}^{2,2}$(${\mathrm{P}}^{5+}$)${\mathrm{II}}^{2}$(${\mathrm{P}}^{5+}$)${3}^{2,2}$.

Rotational spectrum, structure, and intramolecular force field of the ArClCN van der Waals complex

, 1981
The rotational spectrum of the ArClCN van der Waals complex has been assigned using pulsed Fourier transform microwave spectroscopy in a Fabry‐Perot cavity with a pulsed supersonic nozzle as the molecular source.

Intramolecular forces in the water molecule in lithium sulfate monohydrate

The Journal of Chemical Physics, 1975
A study of the low−temperature infrared spectra of varyingly deuterated mulls of lithium sulfate monohydrate has afforded information on the origin of bands due to the vibrations of the water molecule in the solid. Assignments are made for the intermolecularly uncoupled modes which produce these bands in the spectrum and intramolecular coupling force ...

Intramolecular-force-constant model for C60.

Physical Review B (Condensed Matter), 1992
A least-squares fit of a short-range-force-constant model to the 14 Raman and infrared active normalmode frequencies of C 60 has been obtained. The fit is better than 3.8% (in frequency) for any of these modes.

Enhanced Small-Molecule Assembly through Directional Intramolecular Forces

Organic Letters, 2005
[reaction: see text] Directional intramolecular interactions play a critical role in the self-assembly of donor-sigma-acceptor molecules in solution. Amide functions on the periphery of the tricyclic core stabilize a C3-symmetric monomer conformation by intramolecular hydrogen bonding and dipole-dipole interactions.
