    Molecular Geometry: Experiment vs Modeling

    Dear DrDu, Thank you so much. You answer was very helpful. Maybe I should study the basics of microwave spectroscopy. If I may ask one related question about analyzing crystals…. If you look at the diagram of a fully-analyzed and interpreted ice crystal, a number of water molecules...

    Molecular Geometry: Experiment vs Modeling

    All general chemistry textbooks have sections about molecular geometry, explaining that H2O is “bent”, NH3 is “trigonal pyramidal” and CH4 is “tetrahedral”, etc. But in a typical introductory textbook, it’s not easy to figure out how much is from experimental (observed) facts and how much is...

    What is the activation energy of the forward reaction?

    In a typical General Chemistry textbook, quantitative treatments of activation energies begin with the Arrhenius equation, which is given (not derived). When R and T values are properly inserted with the given units, the activation energy comes out with the unit of J/mole. My Question 1...
