A method for estimating the number of nuclei of a preselected isotope in a molecular species starts with an NMR spectrum of a sample containing said molecular species as a predominant substance said NMR spectrum comprising a plurality of signal peaks corresponding to said nuclei. By applying inclusion and ordering criteria one obtains a set of ordered signal peaks the integration of which leads to a set of ordered integrals. Nested outer and inner iteration cycles are carried out wherein for each cycle a trial number of nuclei is assigned to one of said ordered integrals whilst the other ordered integrals are resealed accordingly and rounded to the next integer value so as to yield a …
