Thanks for the clarification on the distance. Regarding the term "London dispersion forces", I am referring to those generated by instantaneous temporary dipole moments due to the movement of the electrons about the molecule. I'd take it that a quadrupole is a permanent type of electric pole...

Excuse me, London dispersion forces.

Thanks a lot. That link was helpful. However, I read that London dispersion forces start "to decay" as R-6, which is a shorter range than that of a quadrupole electric field. Given that BF3 is known to make LDF, doesn't that mean that over such range the electric field of the quadrupole should...

1) By "BF3 has nonvanishing permanent higher dipole moments", are you implying that BF3 as a whole exhibits an identifiable electric pole? 2) Why do the fields fall off very rapidly? 3) When you say that these permanent higher dipole moments are important only for short ranges, how do their...

Hi! Boron trifluoride is a nonpolar molecule due to its high symmetry even though the covalent bonds within the molecule are polar. As a result, the only type of intermolecular forces in BF3 would be the London dispersion forces. I understand that these forces are exhibited by nonpolar...

Admire your passion toward the subject. Clearly you are looking to establish a solid foundation in the subject rather than going for a grad certificate in the same subject but with weaker field knowledge (that is assuming you can get acceptance into the grad program). I'm stuck in a similar...

Greetings everyone! Without wasting any time, I would like to ask for a a piece of advice. I graduated a couple of years ago with a bachelor in biology. Immediately, I stepped into teaching elementary or primary science at some schools. And since science isn't all about biology only, I've...
