Is a complex with the same number of unpaired electrons asthe free gaseous metal ion termed high spin or low spin?
Complex high spin or low spin behavior depends upon the number of unpaired electrons present. According to Hund's law, electron enters orbitals of equal energy one at a time, when all the lower energy orbitals are half-filled, the next electron either paired up the half-filled orbital or jumped into high energy orbital by overcoming the crystal field splitting energy ().
Electron repulsive energy Epairing is the minimum energy required for an electron to pair up the half-filled orbital and crystal field energy () is the minimum energy for an electron to jump into the higher energy orbital without pairing the half-filled orbital electron.
