A connection of the Wigner-Yanase skew information and multiple quantum (MQ)NMR coherences is considered at different temperatures and evolution times ofnuclear spins with dipole-dipole interactions in MQ NMR experiments in solids.It is shown that the Wigner-Yanase skew information at temperature $T$ is equalto the double second moment of the MQ NMR spectrum at the double temperaturefor any evolution times. A comparison of the many-spin entanglement obtainedwith the Wigner-Yanase information and the Fisher information is conducted.

Multiple quantum NMR in solids as a method of determination of Wigner-Yanase skew information
