Various dimer configurations of fluoroform have been studied by means of the GAUSSIAN-70 algorithm using the minimal STO-3G basis set. The largest dimerization energy, 0.68 kcal mol, occurs in an end-to-end linear geometry with a H...F distance of 2.3 and the electron donor molecule tilted...
Given that PFCs have multiple fluorine atoms in their molecular structures, introducing hydrogen bonding receptors into a pore surface might enhance the affinity of MOFs with PFCs. The hydrogen atom on the –NH2group introduced into Cu-MOF-NH2can simultaneously form hydrogen bonds with the three flu...
A relatively stable temporary ring system relies on the donor and acceptor being able to form a conformation in which the two can adopt a suitable geometry and distance. This conformation can shield polarity relative to the open conformation and avoid the desolvation penalty, and therefore the IMH...
(ground2B1and excited2A1and2B1); deviations were less than 0.3 eV in all cases. The calculated optimized structures were in close agreement with experiment. We also made calculations on the two lowest-lying A' and A″ states of the water dimer radical cation at the optimized geometry of ...

Cardiac aging is evident by a reduction in function which subsequently contributes to heart failure. The metabolic microenvironment has been identified as a hallmark of malignancy, but recent studies have shed light on its role in cardiovascular diseases
Is it possible to determine molecular geometry based on a Lewis structure? Explain. Draw the structural formula for 3-3dichlorohexane. Draw the condensed structural formula for the following molecules: trans-2-heptene Determine the molecular point group of CHF_3. Sketch the molecular str...

Conversely, the calculations predict the correct geometry of 57, in which the eight-membered ring adopts an apical–equatorial position. This suggests the tert-butyl groups are responsible for favoring the diequatorial position <1996IC6552>. Density functional theory (DFT) calculations at the hybrid...
