A series of simple QBASIC computer programs is applied for the solution of the equations describing transition probabilities in a two-state system. The transitions are considered to be caused by electromagnetic radiation and a random interaction modeled by the random number generator of a microcompu

โฆ Synopsis
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 with a randomly changing surrounding, modeled by the random-number generator of a microcomputer. The examples illustrate ( ) ( ) the behavior of rotating-frame relaxation time T as a function of correlation time .

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
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
Rotating-frame relaxation measurements have been used in conjunction with spin-spin relaxation rate constants to investigate a conformational transition previously observed in the -10 region of the trp promoter d(CGTACTAGTTAACTAGTACG)2 (Lef~vre, Lane, Jardetzky 1987). The transition is localised to
