## Abstract Poly(__ortho__‐, __meta__‐, and __para__‐γ‐nitrobenzyl‐L‐glutamates) were studied by circular dichroism (CD) and optical rotatory dispersion (ORD) in two helicogenic solvents, hexafluoroisopropanol (HFIP) and dichloroethane (EDC), and two non‐helicogenic solvents, dichloracetic acid (DC

Asymmetric disturbance by deuterium of intrinsically symmetric chromophores such as the car-bony1 group promises to become a fruitful field for theoretical studies of the octant rule. 2 The first example was (3R)-deuteriocyclopentanone (A), prepared3 by multi-step transformation from (t)-
Although numerous examples of asymmetric molecules which owe their chirality to isotopic substitution are known, 3 few are reported3 to display Cotton effects in either optical rotatory disper sion(ord) or circular dichroism(cd). We wish to report the successful
