A simple two-pulse magic sequence (2n+1) ·90°y - Acq(t), where n is an integer, which yields the inversion of the signs of dipolar and quadrupole Hamiltonians and the reverse of the time evolutions was discussed. The process resulted in refocusing of the spin magnetizaiton into magic echo at te=t1÷2 after the second pulse, where t1 is the length of the first pulse. The results of Li NMR echo measurements in powder LiInSe2 applying the pulse sequence were also presented were also presented. The analysis showed that the crystal structure of LiInSe2 belonged to the orthorhombic symmetry.
