TLDR
The title compound, C10H13NO2, crystallizes with two crystallographically independent molecules of similar geometry in the asymmetric unit; the six-membered oxazine rings adopts a half-chair conformation.Abstract:
The title compound, C10H13NO2, crystallizes with two crystallographically independent molecules of similar geometry in the asymmetric unit; the six-membered oxazine rings adopts a half-chair conformation. Neither hydrogen bonds nor π–π interactions are observed in the crystal structure.read more

General definition of ring puckering coordinates
Dieter Cremer,John A. Pople +1 more
TL;DR: In this article, a unique mean plane is defined for a general monocyclic puckered ring, which is described by amplitude and phase coordinates which are generalizations of those introduced for cyclopentane by Kilpatrick, Pitzer, and Spitzer.
