WebApr 4, 2024 · Electron diffraction (known also as ED, 3D ED or microED) is gaining momentum in science and industry. The application of electron diffraction in performing nano-crystallography on crystals smaller than 1 µm is a disruptive technology that is opening up fascinating new perspectives for a wide variety of compounds required in the fields of … WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H. C2 is therefore #2, and C5 is #3. If you assign these priorities to the groups, the sequence 1 → 2 → 3 goes in a counterclockwise direction (S).
