Verification of the Normality of Distribution and Independence of the Results of Quantitative Analysis by NMR *H of High Resolution at Incomplete Resolution of Signals and Their Wide Groups
It is shown that in the method ofNMR 1H ofhigh resolution for wide groups of signals at a low noise level, regardless their overlapping, the consecutive measurements performed during short periods oftime are not independent. Getting data that can be used for statistical processing requires spectra recording with an interval of more than 1 h. For overlapping groups of signals only of the distributions of the measurement errors Hβ è Hγ are compatible with the hypothesis of normality. For other variables and for the error of measuring integrated intensity of the narrow signal allocated against the background of the “hump,”, the hypothesis of normality is rejected at a significance level less than 0.01.
