regardless of the nature of the atoms or molecules composing the substance. This attractive force is called the London dispersion force in honor of German-born American physicist Fritz London who, in 1928, first explained it. This force is often referred to as simply thedispersion force. Because...
For each pair of substances, identify the intermolecular force(s), and predict which one of the pair has the higher boiling point: (a) CH_3NH_2 or CH_3F. (b) CH_3OH or CH_3CH_2OH. (c) H_2O and HF.(d) Hexane CH_3CH_2CH_2CH_2CH_2CH_3 or 2.2-dimethyl...

However, a number of broad biophysical averages for equilibrated representative HDL models (particle geometry and size, as well as molecular distributions) can be determined across long, multi-microsecond timescales by utilising a coarse-grained (CG) force-field model, and these properties can then...

(A) Schematic of the single-molecule (+)-strand RNA synthesis assay, showing binding of an RdRp to a hairpin at the 3′ end of the (−)-strand (gray) of the surface-attached RNA construct. A magnetic bead attached to the RNA construct is subject to a constant force of 25 pN durin...
Various electron donors and electron acceptors have been tested in order to examine the possibility of the application of the Marcus equation to the description of the kinetics of free radical polymerization photoinitiated via photoinduced electron transfer (PET). Variations of the driving force of the...
