The optical rotation of methyl 2‐ O ‐(α‐ D ‐mannopyranosyl)‐α‐ D ‐mannopyranoside is calculated semiempirically as a function of the linkage dihedral angles ϕ (H1‐C1‐O1‐C2′) and ψ (C1‐O1‐C2′‐H2′). Although the rotation calculated for the global energy minimum conformation found in several rigid‐residue modeling calculations (ϕ,ψ = −40°,−20°) is in good agreement with the observed solution rotation, the observed rotation is also compatible with the limited flexibility inferred from more recent relaxed residue modeling calculations on a structurally related rhamnose disaccharide © 1994 John Wiley & Sons, Inc.
