Hi,
In the mulliken population analysis for spin polarized calculation the results are obtained like these...It is understood that the population is split up between the apin up and spin down components.
The question is : 0 C
1.952(spin up or spin down 
2.142(spin up or spin down???) ---------
4.094
Which is the spin up and spin down component?
