High-resolution proton solid-state NMR spectroscopy by phase-modulated Lee–Goldburg experiment
TL;DR: In this paper, a pulse scheme for coherent averaging of spin-spin interactions called phase-modulated Lee-Goldberg (PMLG) is presented, which is aimed at achieving high-resolution proton NMR spectra in the solid state.

TL;DR: High-resilience positive-intrinsic-negative perovskite solar cells are demonstrated by incorporating a piperidinium-based ionic compound into the formamid inium-cesium lead-trihalide perovSKite absorber, and detailed degradation routes that contribute to the failure of aged cells are revealed.
Journal ArticleDOI
Sensitivity enhancement of the mqmas nmr experiment by fast amplitude modulation of the pulses
TL;DR: In this paper, an improved way of doing the multiple-quantum magic-angle spinning (MQMAS) NMR experiment that relies on the use of amplitude modulated pulses was reported.
Journal ArticleDOI
Swept-frequency two-pulse phase modulation for heteronuclear dipolar decoupling in solid-state NMR
TL;DR: In this article, a swept-frequency two-pulse phase modulation (SWf-TPPM) was proposed for solid-state nuclear magnetic resonance applications, which is robust in performance with respect to various experimental parameters, such as, the pulse flip angle, pulse phase, and offset.
Journal ArticleDOI
Cross-correlations in NMR
TL;DR: The phenomenon of nuclear magnetic resonance (NMR) involves placing magnetically active nuclear spins embedded in a gas, liquid or solid phase in a constant, large and uniform magnetic field, causing a splitting of magnetic energy levels.
