    Great video! The reason why mathematical tools like this, so ubiquitous in physics and chemistry, are often introduced without proper motivation and a canonical simple example as a guide, as you pedagogically did, is beyond me. Keep it going!

    dude, the amount of effort put into this video, your explanation and your knowledge are all insane. Thank you so much. Please make more of these videos.

    Very well produced video, I used the same molecular structure and it’s group theoretical structure during my PhD to solve a problem on energy dissipation in physical systems.

    Beautiful presentation! In quantum mechanics I heard vaguely about the problem of adding two angular momenta as finding the irreducible representation, this video really helped me to start understanding what that is about!

    This is beautiful and deserves more views

    Could you also tell what was the impact of this analysis? What did it help discover about NH3? I get the intuition that it will help define all the modes of vibrations and thus the degrees of freedom of motion, but I don't understand how exactly.

      An example of application that I have in mind is to describe optical properties, for example in Raman spectroscopy. If you want to learn more about this I encourage you to read some introduction book on the subject.
      However, I used this example more as an illustration,, made to understand, and be able to represent oneself the basics of Group Theory, which can be generalized for infinite dimensional representations (and even for infinite dimensional groups), that are particularly useful in Quantum Mechanics, and for Particle Physics, which I think are the theoretical subjects where Group Theory is of the greatest use.

      @@vector7669 So... No. Not the degrees of freedom of motion :(
      Thanks for the explanation anyway!

      There surely are applications of these degrees of freedom in chemistry and in Raman spectroscopy as I said.
      But I can't give you more examples of applications since I don't know all of them. (I am a Physics student who wanted to share what I just learned)

    very effecient lecture for physicist. sometimes i dont know why the mathematical approach is used to explain any other subject related to physics like group and representation to physicist.
    But it is the best approach to understand for me.

    If you can’t read the original grouping then to a shaker box for groups you can read.

    IN FRANCE CHEMISTRY IS CALLED PHYSICS (according to the title of this video).
