The periodic table is dominated by nuclei having a nuclear spin larger than one-half, which possess a quadrupolar interaction, or spins having extensively large chemical shift anisotropies. The bottleneck in manipulating such spins is the low bandwidth, hence excitation efficiency, of conventional RF pulses. The demonstration of the spin locking mechanism in quadrupolar spins undergoing magic-angle spinning (A.J. Vega, JMR 96, 50, 1992) allowed the development of efficient quadrupolar-spin 1/2 distance measurements using sequences such as TRAPDOR and REAPDOR. Yet, adiabaticity fails for large quadrupolar couplings or at fast spinning rates, which are common in today's hardware, again due to insufficient RF power. Several developments to overcome this "sudden passage" limit have been proposed in recent years pushing the limit of nuclei that can be analyzed efficiently. I will discuss these advances, and show how our phase-modulated pulse approach provides complete randomization of all powder crystallites and consequently generates macroscopic spin saturation. As a result, distances to quadrupolar nuclei with extremely large couplings can be measured accurately and efficiently (up to frequencies of 10s of MHz), and reliable lifetimes of quadrupolar spins can be determined.

Magnetic resonance spectroscopy (MRS) is a non-invasive technique that allows the measurement of multiple metabolites in the brain in vivo at the same time. These MR visible metabolites are primarily located in the intracellular compartments and preferentially concentrated in certain cell types. For instance, N-acetylasparate and glutamate are predominantly located in neurons, total creatine (creatine + phosphocreatine) and choline containing compounds are found in both neuronal and glial cells, and myo-inositol is thought to be localized exclusively in astrocytes. In the first part of my presentation, I will focus on the application of 1H MRS to study aging of the brain and brain tumors. In the second part of my presentation, I will concentrate on hyperpolarized 13C work in the animal brain which focuses on validating the ability to quantitatively estimate the TCA cycle rate and examination of the effect of various levels of brain activity on the detection of metabolic products from hyperpolarized pyruvate.
