ABSTRACT:
There is disclosed a method of finding a reliable optimum value of a measurement condition in an NMR measurement. This method starts with gaining NMR measurement data while varying the value of the measurement condition to be optimized. Then, a certain property is extracted as a numerical value from the measurement data. A plot is made of the measurement data versus the value of the measurement condition to create a curve. A model equation coincident with the measurement condition, its range, and the certain property extracted as a numerical value is established. Curve fitting is done in which constants of the model equation are varied such that the equation agrees the created curve. The constant values of the model equation and their standard deviation are obtained by curve fitting. An optimum value of the measurement condition is obtained from the results.
