How is the cell constant "d" related to the cell parameters? I know that for the smallest possible diffraction angle d is equal to the longest cell edge. Why?

For the relationships, see See http://en.wikipedia.org/wiki/Bragg's_law

Your second statement seems like a special case to me; I've never used it in my work. Do you have a reference for it?
 

Thread 'Instantaneous dipole moment and orbitals'

Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
