# Sulfur atomic absorption

Would the atomic absorption from FAA for Sulfur be from 3s2 -> 3p4 or 3p4 -> 4s0?

I think according to the electronic partition function, there would be zero electrons in the 4s0 state at the temperatures for ICP N = pe^(-E/kT), where p is the # of electrons in the state.

• It is for the transition $\ce{3s^2 3p^3 4s -> 3s^2 3p^4 }$ of neutral sulfur. articles.adsabs.harvard.edu//full/1994A%26A...286..344R/… – MaxW Dec 23 '15 at 1:24
