Help with Lanthanide 3+ Term Symbols

Hi everyone,

 

I'm doing a project on the magnetic moments of some lanthanide ions. Specifically Ce III Nitrate, Pr III Nitrate, Dy III Nitrate and Er III Nitrate. I calculated the magnetic moments for the ions using their term symbols. I think I may have bodged them up though and I wanted to check with someone whether this was the case.

 

Term symols for the level lying lowest in energy:

 

Ce+3: 2F5/2

Pr+3: 1S0 (J=0 clearly not good)

Dy+3: 8S1/2 (gives a huge magnetic moment)

Er+3: 6H5/2

 

Thanks for any help,

Natski
