Goldman-Shen type experiments do refer to a specific NMR pulse sequence
and the original citation was published in 1966. The following articles
discuss this sequence and its applications.
Hope you find this useful!

Abstract: Decomposition of the proton NMR spectra of linear,
high-molecular-weight polyethylene into a Gaussian function and a
Lorentzian function is discussed in terms of the Wilson-Pake two-component
method (1953) for an inhomogeneous system. The results of a Goldman-Shen
experiment (1966) indicate that spin diffusion does not strongly couple
the two regions. The temperature dependence of the Lorentzian (mobile)
fraction is fitted to a function derived from the relation of English and
Zoller (see Anal. Chim. Acta, vol.189, p.135, 1986). The critical
temperatures give estimates of thermal transitions: T/sub alpha
/=328(+or-5) K and T/sub gamma /=163(+or-4) K. The fraction of Lorentzian
spins excited by the gamma relaxation correlates with the amorphous
content of the sample as determined by differential scanning calorimetry
and X-ray diffraction.
