Contact & corrections
See something wrong? Tell us.
Some lecture slides use AI-assisted illustration, so a structure is occasionally drawn with a bond or an orientation wrong. Where we have caught one, the slide carries a caption saying exactly what is off. For geometry you intend to memorize, work from the live 3D molecules, which load by accession ID from RCSB PDB and PubChem. Each lesson’s Sources & Integrity panel lists every source it uses and who screened it.
Spotted a correction?
It takes a minute and you do not have to say who you are. Tell me which lesson, where on the page, and what looks off. Opening it from a lesson fills the lesson name in for you.
The same form takes requests — a topic you want covered, an interactive that would help, anything the site is missing.
If you would rather write to me directly, or you need to attach a screenshot, email deppmann@gmail.com. I read every one, and a confirmed error gets fixed or the figure comes down.
