Singlet Oxygen-paramagnetic?

[Schwann]

Is singlet oxygen paramagnetic or diamagnetic? I think that since its p subshell is not full it has non-spin paired electrons. Therefore, it is paramagnetic. however, in an answer choice for tpr, it said that long oxygen is diamagnetic. Please help. thanks.

wikipedia "singlet oxygen" then you will find out... but it's too complicated, it's about different energy states in molecular obital

oxygen in the ground state is triplet... i tihnk singlet means that it's diamagnetic
