    Instructor: Catherine Drennan
    Crystal field theory was developed to explain the special features of transition metal complexes, including their beautiful colors and their magnetic properties. In part I of this topic, we consider d-block coordination complexes that have octahedral geometry, and see whether we can change the color of a paper flower dipped in an octahedral cobalt chloride complex just by adding water.

    I had to momentarily pause the video midway to say, I think this lecture, and many in the series have saved my chemistry degree. My teachers are just useless at explaining this content in tutorials and in the written content it's even worse! Why do uni's insist on over-complicating things to the point where you become disheartened? I truly thought I was too dumb to comprehend this topic, now I'm just irritated that it took me so long to find a really good explanation, but I'm also really motivated about the rest of the course. Thank you, Catherine.

      Yeah, that's often the key to understanding any topic. For a person with normal intelligence there's not topic that can't be understood. So if you don't understand something it's usually just not explained very well in terms of the knowledge your already posess.
      So you just need to find people, books, websites etc. that explain in a way that you understand.

      hello!
      if u count in the periodic table the number of groups from the metal (ie grp 1) until Fe, Fe would be under 'group 8'.
      to find the count, u take the group no (so 8) - the oxidation number, 3(u can ignore the +/- sign) which gives u 5.

      One thing that many of our course videos are missing are the recitations. Many courses have recitation sessions where students are welcome to ask questions on anything they are confused on. For example, 5.111 recitations met 2 times per week for 1 hour per session; 26 sessions total; mandatory attendance. For more information, visit ocw.mit.edu/5-111F14. Best wishes on your studies!

    Shouldn't the deexcitation of electrons produce back the green color (500 nm) while all the other colors in the visible range being absorbed for incomplete excitation of the electrons? You know, like the atomic absorption spectroscopy (AAS) principle. 50:00

    "octahedral crystal field splitting energy" when you could just say "delta"

    • @MetalikeV
      @MetalikeV 2 ปีที่แล้ว

      Many energy differences such as those between orbitals, states, etc. are called "delta". This is a course that is defining this particular "delta" for the first time and it makes sense to say "octahedral crystal field splitting energy" multiple times. This isn't a graduate level inorganic course.

      stabilizing energy is different from splitting energy. You need splitting energy to split those d orbitals. The fact that CFSE is 0 is just attributed to the relative stability of the t2g and eg.
