Due to the so called chemical shift, it is possible to get information about the chemical state of the probed atoms. | Due to the so called chemical shift, it is possible to get information about the chemical state of the probed atoms. | ||
The core electrons of the atoms are affected, meaning that the binding energy of the electrons are slightly shifted, when an atom is bonded to atoms of other elements. | The core electrons of the atoms are affected, meaning that the binding energy of the electrons are slightly shifted, when an atom is bonded to atoms of other elements. | ||
