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.

[@CheeksBeClappin]

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

[@RolandBunting]

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

I understand a lot . Thank you so much

[@PhysicalChemistry]

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

[@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

[@toyooo-ms9ss]

So helpful！！

[@PhysicalChemistry]

Thanks!

[@Sci24]

Fine

[@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: th-cam.com/video/YmvJVkyJbLc/w-d-xo.html

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

what?
