Understanding the Energy Differences: Rigid Rotors vs. Harmonic Oscillators

[texans57]

I am currently taking a modern physics course, and we have a take home quiz. I am not savvy in physics at all, much less quantam mechanics, so any and all help is greatly appreciated. My question is:

Explain what is the difference in terms of energy between the ground states of rigid rotors and of harmonic oscillators?

All i can deduce is that because the quantum number L is equal to zero, then E(0)=0 and the lowest ground state for rotation=0. While the lowest ground state for a simple harmonic oscillator is at v(0) and it never touches E(0).

Oh and by the way this isn't the last question I will probably post, because this is a 20 question take home quiz.

Thanks again

As this is a homework question, you're going to have to post this in the homework forum. Go there and read the FAQ on how to post it.

Also, I hope this isn't your first and final trip here! There's always stuff to learn and good people to talk to here!

ok, could you help me then on the homework question forum?

I wish I could. But I don't know anything about this question, sorry.

Also, I think I misread your post. I though you said it would be the last question you posted lol. Thats why I said I hope you wouldn't just leave after that 1 post.
