✦ Synopsis

Carbon-13 CPMAS spectra have been recorded for anhydrous and monohydrate forms of androstanolone. The results are discussed in relation to crystallography. The anhydrous form gives crystallographic splittings in the spectra arising from non-equivalent molecules in the unit cell. The spectra are assigned by comparison with solution-state data.

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
