Abstract
This paper presents the mathematical descriptions of isotopic substitution in terms of neutron scattering lengths and pair correlation functions illustrated by some experimental results. Simple arguments lead to an algorithm for H/D substitution techniques in multi-component systems. The accuracy of the measurements of the coherent part of the scattering and the validity of the corrections are the crucial elements in obtaining useful information. The dominating problem with the corrections is our inability to adequately correct for inelasticity effects because of the relatively large incoherent scattering cross-section for hydrogen. Some examples are given of numerical subtraction techniques with implications for more accurate measurements on two new neutron difractometers being built for measurements on liquids.
