Abstract:
1. A sample container for NMR measurements, the sample container being closed on one side thereof, the NMR measurements performed by disposing the sample container in an environment, having a magnetic susceptibility χ 1 , within an external homogeneous magnetic field B 0 , the external homogeneous magnetic field B 0 extending parallel to a z axis, the sample container being structured to hold a sample substance occupying a volume V within the sample container and having a magnetic susceptibility χ 3 , the sample container comprising: a first wall structure defining an upper partial volume V a second wall structure defining a lower partial volume V a third wall structure defining a center partial volume V a fourth wall structure defining a first interface G a fifth wall structure defining a second interface G B B B F:=(B′ B′ is the first residual field in the center partial volume V 1 ; is the second residual field in the lower partial volume V 2 a ; and F being an average value of any magnetic field A in the sample volume V; and an expansion of A in rotationally symmetrical spherical functions up to order N, wherein a K P
