The solvatochromism (ν max ) of N-substituted Michler's ketonesincluding 4Ј- [bis(2-acetoxyethyl) 2e] and 1,4-bis(4benzoylphenyl)piperazine (BBP, 3)has been studied at 298 K in various solvents with wide ranging dipolarities and hydrogen-bonding abilities. The solvatochromic properties (ν max ) s =
## Abstract The oligo(β‐peptide)s, hexa(α‐isobutyl β,L‐aspartate) (Hex‐AIBLA) and octa(α‐isobutyl β,L‐aspartate) (Oct‐AIBLA), were synthesized in solution by using standard coupling methods. Powder x‐ray diffraction showed that the octamer crystallized in the two helical crystal forms known to exis
