Abstract

The EPR spectrum of doxyl cyclododecane (3,3‐dimethyl‐1‐oxa‐4‐azaspiro[4.11] hexadec‐4‐yloxy) exhibits a large (0.195 mT at −39°C) temperature‐dependent proton hyperfine coupling. Selective deuteration demonstrates that the coupling is to one of the protons in the CH~2~ groups adjacent to the point of attachment of the doxyl ring.

A quantum mechanical protocol for the study of flexible open-shell systems has been applied in a reinvestigation of the isotropic hyperfine coupling constants of the bicyclobutyl radical. Our computations indicate that the most stable structure of the radical corresponds to the exo-form and is chara

## Abstract Unresolvable long range spin‐spin coupling which is not explicitly taken into account in total NMR bandshape analysis is demonstrated to be a potentially important source of systematic error, leading to Δ__H__^≠^ and δ__S__^≠^ values incorrect by __c__. 1 kcal/mol and 2 to 4 cal/(mol K)
