Abstract
A method for analysing a chemical substance containing quadrupolar nuclei to determine a measurable characteristic of the substance. The method includes irradiating the substance with RF energy in a prescribed manner to stimulate NQR of certain quadrupolar nuclei within the substance. Then receiving and processing a signal emitted from the substance to isolate an NQR signal therefrom. Thereafter analysing the NQR signal to obtain a measure of the characteristic of the substance; and providing an output indicative of the measure for analytical purposes. Specific methods for analysing a chemical substance during production thereof to determine a characteristic of the substance indicative of the quality thereof, and for searching for chemicals together with specific systems are also described.
