The animation pairs with this slide:

Fischer's discovery of the configuration of (+)-glucose, described differently in organic textbooks, remains for me a must tell story as the semester winds down. Symmetry tests are timeless. This animation illustrates the end group interchange for sorting glucose (3) and mannose (4). #chemsky 🧪🎉

The final 3D orbital print of the semester is a sweet one! Organic chemistry students @pomonacollege.bsky.social received a model illustrating the anomeric effect. An unexpected bonus (scroll down) was a visit by Cecil the Sagehen! ##chemsky #compchemsky #3dp 🧪

Biomolecular 3D orbital prints were featured this week in organic chemistry @pomonacollege.bsky.social! Class members went home with a student-designed alpha helix model showing i, i+4 N-H---O=C hydrogen bond orbital overlap. #chemsky #compchemsky #3dp 🧪

Monday's 3D print for my organic chemistry class @pomonacollege.bsky.social: an orbital interaction that partly defines the water dimer hydrogen bond. Orbital phases displayed in Pomona-Pitzer colors, appropriate for admitted students day! ELO warming the space. #chemsky #compchemsky #3dp 🧪⚗️🧪

These 3D-printed d-orbital models are ready to parachute into an active learning-based general chemistry class @pomonacollege.bsky.social. Some assembly required! #3dp #chemsky #compchemsky 🧪⚗️🧪

The aldol reaction was front and center in today's organic class! The orbital prints are a Houk group transition state for a lithium enolate + aldehyde reaction and a @pomonacollege.bsky.social student-designed Burgi-Dunitz print. #chemsky #3dp #compchemsky

Happy to be participating in the "3D Printing in Chem Ed" symposium at #ACSSpring2025! Attendees will receive a Burgi-Dunitz orbital model designed by a @pomonacollege.bsky.social student. If you miss the talk, visit their poster and pick one up! Details are below. #ChemSky #CompChemSky #3DP 🧪

A few 3D prints from this week's organic chemistry class: an NBO enolate alkylation transition state and a pi MO model for the enolate of acetaldehyde. We reviewed the SN2 reaction and noted the larger "on-C" orbital of the nucleophilic pi2 MO! #ChemSky #CompChemSky #3DP #3Dprint #3DModels #prusa 🧪

We made these enantiomer keychains for students last spring, and a co-worker converted smaller prints into earrings. I like your CPK earrings!

What's on your chemistry building? When Seaver North Laboratory @pomonacollege.bsky.social was being built in the 1960’s, the architects asked a faculty member what sort of sculpture would be emblematic of the field of chemistry.

Water lone pair 3D orbital prints made their NBO debut in organic chemistry today at pomonacollege.bsky.social! #ChemSky #CompChemSky #3DP #3Dprint #3DModels 🧪
