Line splitting by mechanical rotation in nuclear magnetic resonance

Nuclear magnetic resonance (NMR) measurements for a nuclear spin 1/2 system in an external magnetic field and mechanical rotation in kHz range are reported. NMR signals are measured by the synchronous rotation of a sample and a detector coil under the condition that the rotation axis is perpendicula...

Description
Summary:Nuclear magnetic resonance (NMR) measurements for a nuclear spin 1/2 system in an external magnetic field and mechanical rotation in kHz range are reported. NMR signals are measured by the synchronous rotation of a sample and a detector coil under the condition that the rotation axis is perpendicular to the external field. NMR line splits into two despite the system having a single Zeeman level separation. We analytically show that the splitting originates in the nuclear spin motion under mechanical rotation, and is determined by only the angular velocity of the rotation without any material parameters.
