✦ Synopsis

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 microcomputer. The latter example allows one to introduce the correlation time and to obtain the known relevant equations for the longitudinal 0 relaxation time as a function of .

## Abstract Each of six perfused rat hearts was subjected to 30 min of hypoxia followed by 60 min of reoxygenation. Inversion‐recovery data on the intracellular Na NMR signal, differentiated by a shift reagent, 6 m__M__ Dy(PPP)~2~, were obtained every 5 min, and __T__~1~ values were calculated. The
