A microcomputer ( ffiM PC ) based pulsed NMR spectrometer
This paper describes the design and construction of a personal computer (PC) based pulsed NMR spectrometer to measure spin-lattice relaxation times in solids. The spectrometer works at 10 MHz and produces d. pulses of amplitude 200 Vp_p' The pulse programmer provides various pulse sequences such as 180°-1"-90°and 90°-1"-180°and inter pulse intervals (1")can be computer programmed. The rise and ...
متن کاملSolid-State NMR Spectroscopy
A number of arylamides have been synthesized and found to exhibit potent antimicrobial activities against a broad spectrum of Gram-positive and Gram-negative bacteria while exhibiting low toxicity toward eukaryotic cells. These facially amphiphilic foldamers have a relatively rigid intramolecular hydrogen-bonded arylamide as a framework, which places trifluormethyl versus positively charged ami...
متن کاملDevelopment of Low Frequency Pulsed NQR/NMR Spectrometer
An FPGA based NQR spectrometer has been designed for detection of N nuclei. The digital circuits required for NQR spectrometer i.e Pulse Programmer, DDS, digital receiver have been built inside FPGA. Combining FPGA chip with analog components, NQR spectrometer has been developed. N from NaNO2 is observed using same spectrometer. By adding a permanent magnet of uniform field NMR signal of proton...
متن کاملSolid State Pulsed Power Systems
A Pulsed Power System is characterized by its energy storage system, the energy can be released in the form of a high power pulse to the load, by means of a switching device. The energy storage is usually either of an inductive or a capacitive nature. The limiting device in a Pulsed Power System is often the switch, which limits the pulse peak power and the repetition rate. The conventional app...
متن کاملSolid State NMR Probe Design
The majority of solids NMR experiments today are driven by biological applications in rigid macromolecules, where even the most advanced liquids methods are limited by the spectral resolution they can achieve. Obtaining detailed structural information from NMR of solid samples is often more technically demanding than for liquids because of the absence of molecular tumbling in solids to average ...
