I am writing a lab report for class on PNMR experiment that we did. How come in this experiment we don't worry about the electron spins in our sample? Aren't the electrons affected by the PNMR machine as much as the protons? Isn't there electron proton spin interactions? For some reason, the lab only talks about the proton spins and does not mention the electron spins at all.
Since we did this at room temperature, does this mean that the electrons have so much energy that their spins doesn't even align with the permanent magnetic field, or are they all paired up with other electrons and therefore do not contribute much? I am very confused. Please help!!!
