I'm currently in an advanced laboratory for physics majors, and I'm conducting a pulsed NMR experiment. My partner and I decided that we we're going to measure the T1 and T2 times of Epoxy. The idea is to explore the relationship between curing epoxy and changing T1 and T2 times. We have results to compare to, and they show that T1 increases slightly (by a factor of 1.6) while T2 shortens 27 times more than T1. This is over a three hour curing time, with measurements taken every 30 minutes.
We did obtain data that seems to follow these trends, only our epoxy cured faster than theirs.
My question to any of you who might have some insight is about the physics and chemistry occurring here. Within this experiment we've done tests showing how the concentration of paramagnetic ions and viscosity can affect T1 and T2, but as far as phase changing goes, I don't have a clear idea.
Do any of you have any ideas, recommendations, reading suggestions, or anything that might give me a clue as to how the spin-lattice and spin-spin interactions are being affected here?
Thanks in advance!
