Abstract
An embodiment of a method of detecting a J-coupling includes providing a polarized analyte adjacent to a vapor cell of an atomic magnetometer; and measuring one or more J-coupling parameters using the atomic magnetometer. According to an embodiment, measuring the one or more J-coupling parameters includes detecting a magnetic field created by the polarized analyte as the magnetic field evolves under a J-coupling interaction.
Claims11
A method of detecting a J-coupling comprising:
- (a) providing an analyte in a detector cell adjacent to a vapor cell of an atomic magnetometer, the analyte being polarized, the detector cell and the vapor cell being housed in a magnetic shield that isolates the detector cell and the vapor cell in a static magnetic field;
- (b) applying a magnetic field pulse to the analyte in the detector cell;
- and
- (c) detecting a magnetic field generated by the analyte using the atomic magnetometer as a magnetization of the analyte evolves under one or more J-coupling interactions.
