    One of the best presentations of FT, but i still din't understand why need to use interferometer, can we just use different frequencies of light are shone on the sample simultaneously then do FT? why need interferometer.

    • @keynotechem
      @keynotechem Рік тому

      That could be done. However then you need either a diode array detector or the machinery to move a diffraction grating so that the light crosses a detector as the grating moves. In that case you would not need FT as you are analyzing the energy at each discrete wavelength. UV-vis spectrophotometers use this method. IR wavelengths make the use of the interferometer convenient and less expensive than continuous wave systems (like UV-vis). Diffraction gratings for IR are difficult to make but not impossible. I myself am not familiar with all the limitations and advantages of both approaches but clearly for IR the industry has chosen interferometry for its effectiveness, cost and convenience in this wavelength range.

    @9:52 So does the mass stay the same as you go up in the morse potential? In 8 years surely someone has done the math.

    • @keynotechem
      @keynotechem Рік тому

      Yes the mass remains the same. It is the energy that is increased.

    This gave me a whole new way of looking at bonding! Nobody ever told me about the overlapping circle thing. My question is what do the different colors represent? Why do we subtract when the opposite color circles overlap? I have some ideas, but I don’t want to give myself a false understanding.

    • @blinkletter
      @blinkletter 2 роки тому

      The different shading represents the sign (positive or negative) of the wave function. If we want to have constructive interference (addition) we combine them with the same sign. The other option is destructive interference (subtraction) where we add opposite signs together. Every pair will combine both ways. The constructive combination is lower in energy. Some orbitals (eg pi orbitals) have lobes with opposite sign, that is why these orbitals have two shades.

      Do you know why FTIR need interferometer?

  • @cristianionita8359
    @cristianionita8359 2 роки тому

    Aren't the names of the "sigma" and "pi" MOs derived from the names of the corresponding AOs (provided they interact correctly)?

    • @keynotechem
      @keynotechem 2 роки тому

      The AOs used to create the MOs are sp^n hybrid orbitals and p-orbitals. The sigma and pi nomenclature applies to the MOs that they create when combined. You can make a pi orbital from two p-orbitals (side-to-side) or a sigma orbital (end-to-end combination of two p-orbitals).
