If I have the energy value (in cm-1) of a specific line in the rotational spectrum, how do I find out/assign the correct J''-J' values?
I know the selection rules for J to be +/- 1 for each rotational transition but I'm not sure how you can correctly identify which J value it is if your only...
What is the physical meaning of this approximation? Qualitatively I'm finding it hard to know what differentiates it from other approximation methods...
If I have two galaxies... i.e Ellipticals.. with same mass, size and velocity dispersion approaching each other and merging to form a bigger galaxy, what would be the total energy of the system?
I'm assuming they would be approaching each other from 'infinity', so E=0 initially. I'm guessing...
Trying to derive two functions which are eigenfunctions of the hamiltonian of 2 identical and indistinguishable particles and also eigenfunctions of the 2-particle exchange operator P.
Need some help with my workings I think.Have particle '1' and particle '2' in a hamiltonian given as...
Hi,
I'm currrently doing a project on computing a molecular linelist (set of transitions) for a range of temperatures. I'm wondering though why hey need to be computed.. i.e why can you not measure the transitions in a lab. My molecule I'm looking at is called PH. Why do I need to model the...
Thanks for the reply.
Would I not solve the Schrodinger equation for the electrons and nuclei separately (Born oppenheimer approx) ?
Also, how can I extract the rotation-vibration wave functions and energies for solving for the motion of the nuclei/electrons?
Sorry if this my questions don't...
Hi,
I wasn't sure if this is more Physics/Astro or chemistry because its actually all 3.
i've got some conceptual issues with some tasks at hands, and was wondering if anyone could clear that up for me.
(These questions are all regarding molecules)
1) How do you create a potential energy...
