Video narration
Ek hi d-subshell ke orbitals ki energy alag kaise ho sakti hai? Kaksha ki paanch seats ko metal ion ke chaaron taraf sochiye: chhah ligands octahedral arrangement mein teeno axes par hain. Axes ki or pointing d x2-y2 aur d z2 orbitals ko zyada electrostatic repulsion milti hai, saamne wali seat jaisi takkar. Isliye ve high-energy hain. dxy, dxz aur dyz axes ke beech hain; repulsion aur energy kam hai. In levels ka gap Crystal Field Theory mein Delta o, yani crystal-field splitting, hai. Isliye pehle barabar d-orbitals bhi alag energy rakhte hain.
