Exempel på hur du använder HETERONUCLEAR i en mening

• Nitric oxide is also a heteronuclear diatomic molecule, a class of molecules whose study spawned early modern theories of chemical bonding.
• The rapid changes in proton spin create an effective heteronuclear decoupling, increasing carbon signal strength on account of the nuclear Overhauser effect (NOE) and simplifying the spectrum so that each non-equivalent carbon produces a singlet peak.
• This can serve two purposes: (1) decreasing the deposited energy through additionally adjusting the RF pulse shapes/using composite pulses, (2) elucidating connectivities of NMR nuclei (applicable with both heteronuclear and homonuclear decoupling).
• Accuracy of integration can be improved by inserting a chiral derivatizing agent with a nucleus other than hydrogen or carbon, then reading the heteronuclear NMR spectrum: for example fluorine-19 NMR or phosphorus-31 NMR.
• For example, this extends to methods for resolution enhancement via heteronuclear decoupling, as well as techniques for polarisation transfer between nuclei (to enable structure determination of crystallised and aggregated proteins).
• Her research utilizes the applications of gas-phase reactivity, mass spectrometry, anion photodetachment spectroscopies, and computational chemistry, and her research focuses on: design an optimization of heterogeneous catalysts with lower operating temperatures, oxidation of volatile organic compounds in atmospheric reaction complexes and exploration of electronic structures that arise in heteronuclear lanthanide complexes.
• Upon reaction with tungsten pentacarbonyl, the resulting side-on adduct preserved the dibismuthene unit, while reaction with diiron noncarbonyl yields the a tetracylic heteronuclear iron-bismuth carbonyl compound (see scheme to the right).
