Fourier Transform Multiple Quantum Nuclear Magnetic Resonance

The excitation and detection of multiple quantum transitions in systems of coupled spins offers, among other advantages, an increase in resolution over single quantum n.m.r. since the number of lines decreases as the order of the transition increases. This paper reviews the motivation for detecting multiple quantum transitions by a Fourier transform experiment and describes an experimental appr...

Biophysic evaluation of bone quality-application of Fourier transform infrared spectroscopy and phosphorus-31 solid-state nuclear magnetic resonance spectroscopy.

In this review, we focus on findings obtained with biophysic techniques, Fourier transformed infrared (FTIR) spectroscopy and phosphorus-31 solid-state nuclear magnetic resonance (31P solid-state NMR) spectroscopy, which may allow us to evaluate bone quality and to predict bone strength. FTIR measures the absorption energy that produces an increase in the vibrational or rotational energy of ato...

31P nuclear magnetic resonance spectroscopy of native and recombined lipoproteins.

Native and recombined lipoproteins have been studied by (31)P nuclear magnetic resonance spectroscopy. Very low-, low-, and high-density lipoproteins exhibited characteristic spectra. The main resonances were assigned to phosphatidylcholine and sphingomyelin. Relaxation times for these phospholipids were separately measured in low-density lipoproteins and high-density lipoproteins. The effect o...

Loss of high-energy phosphate following hyperthermia demonstrated by in vivo 31P-nuclear magnetic resonance spectroscopy.

We have used in vivo 31P-nuclear magnetic resonance spectroscopy to study the changes in high-energy phosphates following hyperthermia. Immediately after heating, there is a fall in adenosine triphosphate and apparent intracellular pH and an increase in inorganic phosphate. Following sublethal heating (40 degrees for 15 min), these changes were partial, and they resolved over the subsequent 45 ...
