Dynamic nuclear magnetic resonance DNMR

In this section, some case studies will be presented on the characterization of CMP pad and slurry [17-20] using such advanced analytical techniques as dynamic mechanical analysis (DMA), modulated differential scanning calorimetry (MDSC), thermal gravimetric analysis (TGA), thermal mechanical analysis (TMA), dynamic rheometry, dual emission laser induced fluorescence (DELIF), and the dynamic nuclear magnetic resonance (DNMR). More specifically, these techniques were used to characterize (a) the effect of heat... 

The window of dynamic nuclear magnetic resonance (DNMR) studies concerning reaction rates is relatively narrow, with barriers ranging from AG = 20-100kj mol [60]. Tautomeric processes outside these limits have to be studied by other methods that are much less friendly. 

Exchange Rate Measurements Based on Line-Shape Analysis (DNMR Dynamic Nuclear Magnetic Resonance). Under the measurable exchange rate conditions, two possibilities have been considered ... 

The term DNMR, Dynamic Nuclear Magnetic Resonance, refers to the process of recording and usually computer simulating exchange broadened NMR spectra at a number of temperatures in order to determine mechanistic and/or kinetic information. b The terms fast and slow are used rather than the more familiar labile and nonlabile because the latter imply an intermolecular reaction.
