We have recently demonstrated that polarization transfer using an adiabatic passage through the Hartmann-Hahn condition (APHH-CP) by a variation of the radio-frequency amplitude can substantially improve the transfer efficiency over Hartmann-Hahn cross polarization. Here we show that APHH-CF' can be

Thermodynamic aspects of cross polarization under fast magic angle sample spinning are studied. An extension of the static cross-polarization model is presented which applies to the "sidebands" ofthe Hartmann-Hahn condition. The cross-polarization process for the "sidebands" is not spin-energy conse
