These are all very specific questions related to some lab questions I am supposed to fill out. I was able to do the first part, and know the equation for the Lande factor for the second, but I do not know exactly what the terms are going to be. Secondly, the Doppler question is very confusing to me because the reference material I have does not talk about this at all. Would the equation I want to use be the " full width at half maximum" equation I was able to find on Wikipedia here: https://en.wikipedia.org/wiki/Doppler_broadening? This just seems like the only thing I could find which has terms that I could look up and use from the problem. I have attached the questions for more details on these questions. Thank you.
Doppler width is a classical effect formed by thermal motion of atoms given by Maxwell's velocity distribution. On the other hand, Zeeman splitting is a quantum mechanical effect arising from the coupling of spin with magnetic field, and this involves the Lande g factor. Therefore thermal broadening gives a background effect, which should be properly taken into account while estimating the Lande g factor.
