This video shows how to use the microstates method to determine all the possible term symbols for an atom. It's long, but that's what you have to do to get this level of detail!
I have watched multiple term symbol videos here and yours is by far the best in terms of simplicity and effectiveness. Definitely have alleviated my struggle with the way how my professor taught it (your method is a bit more paper heavy, but definitely much easier to understand and execute)
Thanks! It *is* a lot of writing, and there are shortcuts that can get ground states, but this way guarantees that you get everything. I'm glad you found it helpful.
Does the same method outlined in step 3 work if there is only one electron, and therefore a spin range of [ 1/2, -1/2]. As the L ranges are integers and cannot be achieved with a single electron (due to a single electron of half spin not being able to achieve a value of +1, 0, -1 etc). That may have been a poor explanation but hopefully you understand what i mean.
i think that she got too less time to explain it in the lecture and ofc u cant just pause like on youtube to think this through... anyway you did an excellent job! may i ask you where do you come from? my first guess is USA east coast
It's longer, but you just have to write out every possible configuration. For 3 electrons, you'll have spin tables (Step 3) for +3/2, +1/2, -1/2, and -3/2. That's two actual tables due to symmetry, but the number of possible combinations will be bigger for the possible range of L (+2, +1, 0, -1, -2)!
This video is super helpful, I'm currently using your method for my masters program in spectroscopy. I was wondering if you have a video for excited state term symbols?
Glad this was helpful! I'm taking suggestions for other topics here: ruclips.net/video/-5fpbijpYMA/видео.html Let me know if there's anything else you find vexing.
John Harkless Well i have a inorganic chemistry final coming up and I'm really struggling with the character tables, SALC's, (ir)reducible representations etc. For example, one question is: to which symmetry representations do the group orbitals (SALCs) of the H 1s orbitals and s- and p- orbitals of B in BH3 belong to? If you could give an explanation of how this works or any tips and tricks on how to tackle these kind of questions would be great. Would really appreciate it. Thanks man!

This topic was taught in my class, but not nearly as well, so thank you again for the help! Your explanations are very clear!
You are the greatest man that ever lived - Thanks from australia
Thanks! This one was a monster to put together. Based on the positive feedback, it seems like it was necessary.
Amazingly useful! Thank you very much for taking the time to explain this in such detail and clarity.
You're welcome. I'm glad this could help. Microstates were a monster problem when I was learning.

Luke Newbury, the short answer is that the steps still work the same, but you'll have half-integer numbers instead of the - 1, 0, +1 as before.
Awesome, thank you for the prompt reply.
Thank you sir, Great explanation...

Santosh Kumar Behara Thanks! Glad you found it useful; feel free to tell others.
Thank you Soooo much!! I could not find one clear explanation of this, in any of the texts I read. Fantastic!!!!!!!
Thank you so much.. Perfect explain
thanks for this great video! way better explained than my prof...
greetings from austria :)
Max Anderla glad to hear that this helped. It's a crazy difficult topic!
i think that she got too less time to explain it in the lecture and ofc u cant just pause like on youtube to think this through... anyway you did an excellent job!
may i ask you where do you come from? my first guess is USA east coast
Max Anderla Good guess! I'm originally from the southern USA, but currently on the East coast!
just one more question: how does this work with an 3-electron system? i tried to figure it out with p^3 but couldnt do it...
It's longer, but you just have to write out every possible configuration. For 3 electrons, you'll have spin tables (Step 3) for +3/2, +1/2, -1/2, and -3/2.

This video is super helpful, I'm currently using your method for my masters program in spectroscopy. I was wondering if you have a video for excited state term symbols?
I don't, explicitly. I think you could probably map the excited state to the list of terms you get at the end?
Cleverness turned video! Greetings from México
Excellent sir... Very nice....
Thank you so much! I finally understand how to do these problems!
Brian Trat, glad this was helpful! Feel free to share this or other videos.
This explanation was illuminating as hell. Thanks.
Thanks. This topic is a monster, so I'm glad I was able to help you tame it a little.
well explained Sir!
greetings from germany :)
Thanks!
Thanks KING!
great teacher
Thanks! This has been a long time coming. Microstates can seem crazy, so I figured I would try to help.
Thank you sir, I had some difficulties eliminating the microstates after assigning the orbitals, but now it's all good.
Thank you!! You're an inspiration!
Thank you so much! this makes way more sense than how my prof explained it.
I'm glad this helped you!
Very helpful, very clear explanation! Thank you!

Hidde Joosten I'll have to dig in my undergrad crates to get the notes together. It's a challenging topic for sure!
Thank you so much can you go over the molecular orbital diagram for pi bonded complexes and pi donating complexes (ag,t2g,eg)
