Spectroscopic notation Definition and 13 Threads

I think there are different conventions. Once I worked with XPS, and there we used the spin quantum number, the letter for the orbital, and a number for the energy leverl I think, to characterize photoelectrons. Another notation uses, to characterize an atomic state, the convention...

Homework Statement [/B] Consider the hydrogen atom in the 42F5/2 state. Take into account the effects of finestructure (spin-orbit coupling). (a) Write down the spectroscopic notation of the state that the 42F5/2 is degenerate with, in the absence of an external magnetic field. (b) Calculate...

Question (a) Write down the quantum numbers for the states described in spectroscopic notation as 2S3/2, 3D2 and 5P3. (b) Determine if any of these states are impossible, and if so, explain why. (Please note that these could describe states with more than one electron.) My Attempt A) I came...

Hello. I think excited states of Argon atom is described by j,l coupling written as (2s+1)[K]J. However, when I read some papers describing cross section data for Argon atom, data are quoted with strange notation, Paschen notation. I tried to study the Paschen notation and found that its form...

Hello, I've been studying spectroscopy in organic molecule and I came across an old data from 1934. 280(5b)(k,i±e), 297(1vd)(e), 354(1vd)(k,e), 378(1vd)(k,e), 398(Ovd) (e), 426(1vd)(k,e), 766(Ovd) (k,e), 807 (Od) (k,e), 817 (lb) (k,e), 842(1vd)(k,e), 862(2)(k,e), 878(3)(k,e), This is a piece...

Homework Statement What are S, L and J for the following states: ##^1S_0, ^2D_{5/2} ^5F_1, ^3F_4## Homework Equations The superscript is defined as: 2S + 1 The subscript is defined as: J = L + S The letter denotes the angular momentum number (s, p, d, f...) starting at s = 0. The Attempt at a...

Homework Statement Consider a ^3D_X where X=3/2 state. a) What are the possible values of S, L, J and J_z? Homework Equations Spectroscopic notation for this LS coupling is ^YL_J where Y=2S+1. J ranges from|L-S| to |L+S| The Attempt at a Solution Since L=2 and S must be equal to 1, how can...

I'm a little confused about what is actually meant by the JP = 1/2 + octet. I'm pretty sure it means the particles must have spin 1/2 in the ground state (l=0) and an even parity but what I'm confused over is the absence of an sss, uuu or ddd state. I understand that this would give I3 = 3/2...

Homework Statement find each of the angular momentum quantum numbers and the spectroscopic notation of the ground state electron configuration. Homework Equations n2s+1L J The Attempt at a Solution so for "each of the angular momentum quantum numbers" I am just finding the L in...

Homework Statement see atachment Homework Equations The Attempt at a Solution http://en.wikipedia.org/wiki/Spectroscopic_notation no idea why I'm wrong? does the n=4 make it go into the next orbital or something? Thanks

Forgive me if this has already been discussed. I've been searching and haven't found it. When summing the spin of an atom in the Russell-Saunders coupling scheme, some texts include the spin of an odd nucleon, and some don't. For example, if an atomic energy state is described as ${3}^P_{2}$...

Homework Statement This is a problem that was on a quiz. The quiz has already been graded and handed back and the faculty member graded very gently. (This means I passed when I think should not have.) I have thought about the answer I gave at the time and it was pretty bad. My current...

Greetings, I'm a bit confused about the notation for multi-electron orbitals. For example, you have the notation ^{1}D_{2}, which mean a singlet with S=0 L=2, J=2, right? Now I've come across the notation (in Slater) ^{1}D_{2}^{0} What's the deal with the extra superscript 0?
