#vsepr — Public Fediverse posts

Visited #London for the first time and stayed near #UCL (University College London) where Ron Gillespie developed the ‘#VSEPR rules’ of molecular geometry before moving to #McMasterU in #Canada for a long and distinguished career as Professor of #Chemistry.

I couldn’t resist getting a Rules Vesper cocktail at the nearby Rules restaurant and toasting the memory of my dear old Professor and then collaborator!

This might be an opportune time to mention that an electron’s #doppelganger was shown to provide the physical basis for Ron Gillespie’s #VSEPR model of #molecular geometry. #McMasterUniversity #Chemistry #Physics #QuantumTheory #QTAIM #TenetMedia

Nostalgic toot warning! ⚠️

We often celebrate birthdays 🎂 of #scientists whose research was impactful on our lives.

But is marking the publication anniversary of research that was a #TurningPoint in our #science career a thing? 🤔

If so, a 40th anniversary toot to a #JACS paper that will remain relevant as long as #chemistry students learn about Ron Gillespie’s #VSEPR model and #chemists use it to intuitively understand the shapes of molecules.

When I was a teenager in #Toronto I went to an #EltonJohn concert in #MapleLeafGardens in the #YYZ and learned about the #VSEPR model of molecular geometry from its creator, Ron Gillespie himself, at #McMasterUniversity in the nearby #Hammer. https://en.m.wikipedia.org/wiki/Ronald_Gillespie

Note that I did NOT go to a John-Taupin concert, nor did I learn about the Gillespie-Nyholm rules. #WordsMatter #chemistry

Gary Schrobilgen, Professor of #Chemistry at #McMasterUniversity 🇨🇦 has been named the recipient of the 2024 International Henri Moissan Prize (named after the French chemist who discovered fluorine)! 👏

What is your favorite molecule/ion synthesized by Gary? Mine is the pentagonal planar ion XeF5(-1). It’s great for questions on #VSEPR with answers not on @Wikipedia !
