摘要：
A method is presented by which pure absorption spectra can be derived from spin echoes with a symmetric envelope amplitude, but with arbitrary phases φ in the centers of the echoes. It is shown that without any phase correction, absorption spectra can be obtained in which the amplitudes of the spectral lines are either proportional to cos φ or sin φ, or independent of φ. As an example a T2 measurement of 1,1,2-trichloroethane is given. © 1979.
