Check Answer and Solution fo Co-ordination number of central metal Co(III) ion : 6 Correct the number of electrons for the charge and then see if any are unpaired. What about #NO^(+)#? A paramagnetic electron is an unpaired electron. Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials with unpaired electrons.The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei.EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. So for diamagnetic all electrons are paired. Diamagnetic Molecules :: If the Electronic configuration of a molecule has only paired or spin paired electrons, then that molecule is said to be Diamagnetic.
