Although the “proper” name of the technique should be electron magnetic resonance (EMR) to correlate with the NMR technique, this term has never been internationally adopt固执点好 发表于 2025-3-30 20:14:43
Beschreibung neuerer Kraftwerke,rotein. For calcium-binding proteins, the NMR active isotope .Ca is a quadrupolar (I = 7/2) nucleus that produces broad peaks when bound to a protein (.–.) Although much useful information can be gleaned from studies of this nucleus (.,.), it is impossible to resolve the signals for individual calci葡萄糖 发表于 2025-3-30 23:52:28

The most abundant calcium isotope, .Ca, has a spin quantum number I = 0 and is therefore not observable by NMR. However, .Ca has I = 7/2 and is in pridecode 发表于 2025-3-31 02:54:05
