Table 1. Theoretical triplet phases according to structure models NH3 (Ψ) and N3e (
) of D-alanine for a few secondary H reflections seen in Fig. 1 ▸
.
Letters b/r stand for blue/red BC lines. Experimental peak asymmetries are given in terms of parameter
, equation (6). Relative amplitudes and positions are estimated by the W and
values, respectively.
