Rotational Constant

[@cyrussharma3973]

Fantastic breakdown of the topic. Really helped to make sense of all the different components of the equations and how they all link. Thank you!

[@PhysicalChemistry]

You're welcome, I'm glad the detail was useful for you

[@mortezakhoshbin]

I cant believe how sweet you are telling this concepts as a story. your story makes me get up at 5 o clock to listion to that.THANK YOU

[@PhysicalChemistry]

I think the topics are easier to learn when they are connected together. Your dedication is impressive.

Hi sir i am from tamil nadu .i am easily understood this topic sir thank you so much

[@PhysicalChemistry]

Great! I'm always happy to hear how far these videos have spread, and I am glad they have been useful to you

[@vanyaahmadaziz2964]

I just wanna say this is very helpful to understanding this lesson and I can say it's easy-peasy after I LESSEON TO YOUU thank you so muchhhhh 👏❤

[@PhysicalChemistry]

Thanks, I'm happy to hear that

[@vanyaahmadaziz2964]

please I have a question how to convert the unit of rotational constant B to HZ and cm-1

[@PhysicalChemistry]

Use equations like E = hν and E = hcṽ. If you have B in units of energy, divide by Planck's constant to get units of frequency. And divide by Planck's constant and the speed of light to get wavenumbers.

@@PhysicalChemistry Thank you so much

Hi thanks for the nice explanation, but i have a quastion: Schould not energy has a negative sign? thanks :)

[@PhysicalChemistry]

No, not for rotational energy. It's kinetic energy, and is always greater than zero. Here's a video where we obtained the (positive) energy for the ground state, if you want to check the details: kzbin.info/www/bejne/fHzOYXyViLqKlZI
