The u.v. absorption data for a series of cyclic and acyclic linear conjugated dienamines are reported. The morpholine and pyrrolidine groups in conjugation with the double bond system are shown to exert an auxochromic shift of +50 and +63 nm, respectively, and the effect of alkyl substituents is shown to vary with their position in the carbon chain (i.e.α, β, γ, or δ to the amino-group).
