zero point energy inquiry
« on: November 21, 2004, 08:17:35 AM »
Greetings everyone!

I would like to ask which of the ff. transitions occur at zero point energy: electronic, vibrational or rotational transitions: electronic, vibrational or rotational transitions?

Hope to hear from u guys soon.  Thanks.

Regards,
Tashkent

Hello, physical chemists here :o!?  I think I'm answering my own question :P
 :-X

I read from Alberty that zero point energy is hv/2, where v is the vibration frequency.  Does this mean that zero point energy occurs only during vibrational transitions?  Would appreciate confirmations from expert physical chemists here...

Thanks a lot,
Tashkent :-\

Yes. Zero point  energy is the energy of the ground vibrational state.
Even at absolute zero temp, the zero point energy exists and keeps molecules vibrating in the ground state.
