FIELD: physics.SUBSTANCE: invention relates to spin magnetic resonance application. A method of performing nuclear magnetic resonance spectroscopy (NMR) a sample under investigation comprises generating nuclear spin magnetic resonance random emission radiations by placing the sample in a NMR magnetic environment; detecting spin resonance random emission radiations from the sample; converting the detected NMR signals for processing; correlating the converted NMR signals to obtain an NMR auto-correlation function; and obtaining spin resonance properties of the sample from the NMR auto-correlation function. To perform nuclear magnetic resonance imaging (MRI) of a sample under investigation, generation of nuclear spin magnetic resonance random emission radiations is performed in a MRI magnetic environment. In a second version of performing NMR, an NMR power spectrum is obtained from the converted NMR signals. Similarly, a second version of performing MRI, an MRI power spectrum is obtained from the converted MRI signals. A method of performing electron spin magnetic resonance (ESR) of a sample under investigation comprises generating spin magnetic resonance random emission radiations by placing the sample in an ESR magnetic environment; detecting spin resonance random emission radiation from the sample as source ESR signals; converting the ESR signals for data processing; correlating the converted ESR signals to obtain an ESR auto-correlation function; obtaining an ESR power spectrum from the ESR auto-correlation function and obtaining electron spin resonance properties or constructing electron spin resonance property images of the sample from the ESR auto-correlation function and/or ESR power spectrum. For the second version of ESR, the ESR power spectrum is obtained from the converted ESR signals and the ESR auto-correlation function is then obtained from ESR power spectrum.EFFECT: use of the invention improves spectral resolution and safety for patients.23 cl, 8 dwg
