Symmetry Elements of Molecules

Identifying the symmetry elements of molecules requires that they be visualized in three dimensions.

Thank you so much for these lectures! I am taking a PChem course and it is really helpful having these videos to review. Much appreciated!

[@PhysicalChemistry]

Thanks for the comment. I'm glad they're helpful

[@alessandrarosales326]

im taking inorganic chem and this is helping visualize the rotations so much better.

[@mariam.7271]

nicely done!

[@kammarisunitha4052]

Nice sir

[@nikolastanic9818]

Great content! It helped a lot!

[@PhysicalChemistry]

I'm happy to hear that -- that's the goal of these videos

[@tina_tan]

I understand a lot . Thank you so much

[@PhysicalChemistry]

You're welcome. I'm very happy to have helped

For the NH3 at 4:38 would it then be a 3σv, being more specific?

[@naomimorgan5709]

yes

[@PhysicalChemistry]

Yes, that's right. The 3 mirror planes (σ) could be described more specifically as vertical mirror planes (σᵥ), since they are parallel to the principal axis of rotation

[@toyooo-ms9ss]

So helpful！！

[@PhysicalChemistry]

Thanks!

[@chunhutan2562]

Amazing! Are you really writing/drawing in the inverse direction?😀

[@PhysicalChemistry]

No, if I was doing that, it would be a disaster. Especially in a lecture where I have to talk about rotations and mirror images. Here's how it's done: ruclips.net/video/YmvJVkyJbLc/видео.html

Fine

[@user-sg8oe8ot6w]

There are no elements of dynamical symmetry, examples with intramolecular rearrangement of the molecular parts, possessing symmetry in space of the impulses.

So much work for something that doesn’t fucking matter lmao
