TLDR
A general theory is presented for selective or “tailored” excitation by an arbitrary modulation of the radiofrequency transmitter signal, and it confirms earlier conclusions that the frequency-domain excitation spectrum corresponds to the Fourier transform of the transmitter modulation pattern.About:

Effect of Photic Stimulation on Human Visual Cortex Lactate and Phosphates Using 1H and 31P Magnetic Resonance Spectroscopy
TL;DR: The finding that PS caused decreased PCr/Pi is consistent with the view that increased brain activity stimulated ATPase, causing a rise in ADP that shifted the creatine kinase reaction in the direction of ATP synthesis.

Extended phase graphs: Dephasing, RF pulses, and echoes ‐ pure and simple
TL;DR: The present review investigates the foundation of EPGs and sheds light on prerequisites for adding more advanced phenomena such as diffusion and focuses on limitations and simplifications as well recent extensions within the EPG concept.
Journal ArticleDOI
Use of high-resolution proton nuclear magnetic resonance spectroscopy for rapid multi-component analysis of urine.
TL;DR: These studies show that high-resolution 1H NMR spectroscopy provides a fast, simple method for "fingerprint" identification of urinary compounds, and determinations of creatinine by 1h NMRSpectroscopy compared well with those by an independent chemical assay based on the Jaffé reaction.

Relaxation Effects in Nuclear Magnetic Resonance Absorption
TL;DR: In this article, the authors studied the effect of the thermal motion of the magnetic nuclei upon the spin-spin interaction in a rigid lattice and the line width of the absorption line.

Image Formation by Induced Local Interactions: Examples Employing Nuclear Magnetic Resonance
TL;DR: An image of an object may be defined as a graphical representation of the spatial distribution of one or more of its properties as a result of interaction with a matter or radiation field characterized by a wavelength comparable to or smaller than the smallest features to be distinguished.
Journal ArticleDOI
Two‐dimensional spectroscopy. Application to nuclear magnetic resonance
TL;DR: In this article, the possibilities for the extension of spectroscopy to two dimensions are discussed, including the elucidation of energy level diagrams, the observation of multiple quantum transitions, and the recording of high-resolution spectra in inhomogenous magnetic fields.
Journal ArticleDOI
Relaxation Processes in a System of Two Spins
TL;DR: Abragam and Pound's method for the calculation of the longitudinal relaxation time was extended to the transverse relaxation time in this paper, which gave rise to a steady and transient Overhauser effect.
