title = "Double-quantum NMR spectroscopy based on finite pulse RFDR",
abstract = "We demonstrate that the finite pulse RFDR sequence (J. Chem. Phys. 114 (2001) 8473) can be used effectively for 31P double-quantum NMR spectroscopy at a spinning frequency of 10 kHz. The 31P NMR data measured for hydroxyapatite and octacalcium phosphate show that sizable double-quantum excitation efficiency can be obtained with the ratio of the recoupling field to spinning frequency set equal to 1.67.",
