Charge–transfer organic crystals: Molecular vibrations and spectroscopic effects of electron–molecular vibration coupling of the strong electron acceptor TCNQF4
Moreno Meneghetti,Cesare Pecile +1 more
TL;DR: In this article, a vibrational analysis of the title compound and of its monomeric radical anion is reported, based on the Raman depolarization ratio measurements and on infrared data of solutions of both neutral and ionic species as well as on polarized infrared spectra of oriented crystals of the neutral molecule.
Journal ArticleDOI
Direct detection by atomic force microscopy of single bond forces associated with the rupture of discrete charge-transfer complexes.
TL;DR: These experiments establish that binding forces due to discrete chemical bonds can be detected directly in AFM pull-off measurements employing SAM modified probes and substrates, and compare favorably with a contact mechanics model that incorporates the effects of discrete chemical Bonds, solvent surface tensions, and random contact area variations in consecutive pull-offs.

The vibrational force field of halogenated aromatic molecules. II. Out-of-plane vibrations of fluoroaromatics
TL;DR: In this paper, a quadratic force field for the out-of-plane vibrations of florobenzenes was determined, and the present field is in excellent accord with the chlorobenzene field of Scherer and with the benzene fields of Whiffen and of Kydd when due allowance is made for differences in coordinate definitions.

Prediction of vtbrational spectra by the CNDO/2 force method: I. Out-of-plane vibrations of benzene and fluorobenzenes
TL;DR: In this paper, the out-of-plane force constants of benzene and 12 fluorobenzenes have been calculated by the CNDO/2 force method, and two empirical scaling factors had to be applied to obtain good agreement.
