Abstract
GENERAL equations have been derived for the second moment of a nuclear magnetic resonance line in an oriented polymer1 on the basis of the Van Vleck formula2. These equations were verified for ‘monocrystalline’ polyoxy-methylene obtained from a trioxane monocrystal by solid-phase radiation-induced polymerization.
