Cross-polarization (CP) is an indispensable part of solid-state nuclear magnetic resonance (NMR) spectroscopy to enhance sensitivity and extract structural information. However, the most common CP experiments are susceptible to anisotropic interactions (CSA and QC). A new OC pulse, OPTIANS will be presented which shows 50% better 19F-7Li/23Na PT efficiency compared to ramped CP, both in simulations and experimentally.
