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!

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

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 3 года назад

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

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 👏❤

Thanks, I'm happy to hear that

@vanyaahmadaziz2964 3 года назад

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

@PhysicalChemistry 3 года назад

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.

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

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FKk0I_SUW_0.html
