Question

6–26. Show that the molecule 016016 has only odd rotational levels in its ground electronic state.

Answer 1

Because of unpaired electrons in 2 px and 2py level Oxygen molecule has odd rotational level in the ground electronic state.

# 2p. They 160 க்கர் மலை Energy *25 o- Atom O-Atom h AO." 02 Molecule L M.O. The electronic configuration of Oz molecule is ris² * 152 525² & 25² r2p 2² (+1 2 2 2 ² 13 2 p ; ²) in 2px 't zpy Since I 2px & 2 By contain only 1 unpaired election each OL molecute is paramagnetec in nature ie. Two unpaired electrons in the antibonding M.o. and these two unpaired elections are unidirectional in 02 molecules. and odd rotational level in the ground electronic Stalé
