β¦ Synopsis
A series of QBASIC computer programs has been developed for the solution of equations that describe the creation and loss of quantum coherence in a two-state spin system. The coherence is considered to be created by electromagnetic radiation and afterwards lost by interaction with randomly changing surroundings α the latter being modeled by the random-number generator of a microcomputer. The examples ( ) explain the equations for transverse relaxation time T as a function of correlation time 2 ( ) .

This paper is a continuation of previous works, in which QuickBasic computer programs are used to solve equations that describe the loss of quantum coherence in a two-state spin system, in the present case spin-locking conditions are applied. The coherence is considered to be lost by interaction wit
As a continuation of previous works, QuickBasic computer programs have been developed for the solution of the equations describing the transfer of polarization in a system of coupled spins, when spin-lock conditions are applied. The transfer is considered to take place through a simple model of dipo
The transverse NMR relaxation times of hydrogen nuclei of water absorbed in white spruce sapwood [Picea glauca (Meunch) Voss] were measured for moisture contents in the range from 5 to 176%. The spin echo amplitudes resulting from the Carr-Purcell sequence decay nonexponentially suggesting the poss
This paper presents a novel method of measuring the droplet size in oil-in-water emulsions. It is based on changes in the NMR transverse relaxation rate due to the effect of microscopic magnetic susceptibility differences between fat droplets and the surrounding water. The longitudinal and transvers
