Process Change in magnetic nature Bonad order change N 2 → N 2 + Dia → Para 3 → 2 . 5 NO → NO + Para → Dia 2 . 5 → 3 O 2 → O 2 - 2 Para → Dia 2 → 1 O 2 → O 2 + Para → Para 2 → 2 . 5

Process	Change in magnetic nature	Bonad order change
$N_{2} \to N_{2}^{+}$	Dia $\to$ Para	$3 \to 2.5$
$NO \to {NO}^{+}$	Para $\to$ Dia	$2.5 \to 3$
$O_{2} \to O_{2}^{- 2}$	Para $\to$ Dia	$2 \to 1$
$O_{2} \to O_{2}^{+}$	Para $\to$ Para	$2 \to 2.5$
