Abstract:
1. Method for examining a sample by means of magnetic resonance spectroscopy including the execution of a utilization experiment comprising the following steps: a spatially substantially homogenous main magnetic field is generated in a measurement region containing the volume of the sample using a main field coil which encompasses the measurement region, which main field aligns the atomic spins of the sample longitudinally with respect to the field lines, wherein said main magnetic field has a time-dependent progression and has an amplitude progression in the form of at least one pulse which follows a defined time function within a defined time window; from a point in time before or at the commencement of the defined window of time the sample is subjected to a high frequency electromagnetic excitation pulse whose frequency band, amplitude and duration are selected such that within the time window a magnetic resonance signal appears; the temporal progression of the magnetic resonance signal is measured and its spectrum is analysed.
