Manipulation of spin-1 solid-state targets

The spin-1 nuclear magnetic resonance (NMR) lineshape for polycrystalline materials can be manipulated with selective radio frequency (RF) to alter the overlapping absorption lines in a dynamically polarized target. This process can be performed in solid-state targets either in a frozen spin state or during continuous microwave pumping to manipulate the vector and tensor polarizations of the spin-1 target. In this paper, we present an analytical description of the spin energy levels responsible for the dynamics in the continuous wave NMR spectrum under RF, as well as a new simplified analysis of the lineshape itself that relies on three basic conditions. These conditions can be used to measure the vector and tensor polarization in an RF-manipulated signal in real-time or to simulate the spin-1 NMR lineshape's response to locally applied RF irradiation. The analytical description of the RF-manipulated lineshape as well as the resulting simulations can be used to optimize the figure of merit in high-energy and nuclear scattering experiments using spin-1 solid-state targets.
