Atom Angles

Postby Emily_Stenzler_2H » Wed Nov 25, 2020 9:47 pm

The concept of the angles between the atoms changing based on electron lone pairs etc. makes sense, but does anyone know how exactly scientists discovered these angle measurements? Were these angles every actually measured, or are they assumed to be what they are based on other experimental observations and logic?

I searched it up and apparently they were discovered through various spectroscopic methods and diffraction methods. I don't think it is important to know how the geometry was found other than through experimentation.

They used rotation and vibrational spectroscopy, and X-ray diffraction to find the angles between the atoms in a molecule.
