The complex NMR study of the magnetic structure of LiCu{sub 2}O{sub 2} multiferroic has been performed. It has been shown that the spin spirals in LiCu{sub 2}O{sub 2} are beyond the ab, bc, and ac crystallographic planes. The external magnetic field applied along the c axis of the crystal does not change the spatial orientation of spirals in Cu{sup 2+} chains. A magnetic field of H{sub 0} = 94 kOe applied along the a and b axes rotates the planes of spin spirals in chains, tending to orient the normal n of spirals along the external magnetic field. The rotation angle of the planes of the magnetic moments are maximal at H{sub 0} Double-Vertical-Line b.
