Description
Understanding the NMR lineshape of solid deuterated materials has become of interest due to upcoming measurements of the tensor polarized observables $A_{zz}$ and $b_1$ at Jefferson Lab. This talk will describe a new computational model based on simple spin-flip transition calculations that accurately describes the NMR spectra of deuterated materials that have undergone both dynamic nuclear polarization (DNP) and semi-selective saturation radio frequency (ssRF) techniques to enhance the vector and tensor polarization. This model correctly predicted the imaginary portion of the deuteron lineshape, which can be utilized along with the typical real NMR signal to reduce systematic uncertainties in lineshape analysis due to mistuning of the NMR measurement tank circuit.
