Measurement of Pol Ymerization Degree of Condensed Phosphates by Solid-state Nmr
Measurement of polymerization degree of condensed phosphates was examined by solid-state NMR. Broad peaks of the NMR of endand middle-PO4 groups of condensed phosphates were observed at about 1 and -20 ppm, respectively. The NMR. peak area ratio (Ro) of middle-PO4 group to end-PO4 group has the following relation with the polymerization degree (n) of polyphosphate: Ro (middle-PO4/end-PO4) = (n-...
متن کاملDetermination of BKW Equation of State Parameters via Measurement of the Detonation Velocity in Condensed Explosives
An optical system has been redesigned and used to measure detonation velocity as a function of condensed explosive density for RDX, HMX, PETN. These measurements are then used to determine and fine tune parameters appearing in the BKW (Beker-Kistiakowsky-Wilson) equation of state for gases at extremely high pressures. Steady state form of conservation equations along with the BKW state equation...

متن کاملHigh-Precision Measurement of Internuclear Distances using Solid-State NMR
Today, nuclear magnetic resonance (NMR) is among the most efficient tools in structural studies. Measurement of interatomic distances is the most common way of determining high-resolution structures of molecules using NMR techniques. In this article, we describe NMR techniques for static powder samples, based on a two-dimensional single-echo scheme, enhanced with adiabatic cross-polarization. T...
متن کاملAccurate measurement of C – N distances with solid-state NMR
Solid-state NMR technique for measuring distances between hetero-nuclei in static powder samples is described. It is based on a two-dimensional single-echo scheme enhanced with adiabatic cross-polarization. As an example, the results for intra-molecular distances in αcrystalline form of glycine are presented. The measured NMR distances C(2) – N and C(1) – N are 1.496 ± 0.002 Å and 2.50 ± 0.02 Å...
