Nuclear magnetic resonance spectroscopy was combined with X-ray crystallography to determine the solution and solid-state conformations of glyburide (C23H28ClN305S). In solution, there is apparently free rotation about several of the single bonds. Crystals of glyburide belong to space group P2,ln wi
## Abstract The solidβstate and solution conformations of (+)βchelidonine (1), a biologically active alkaloid, were determined by Xβray diffraction and ^1^HβNMR spectroscopy, XβRay diffraction analysis revealed a conformer with B/C β__anti__βtypeβ __cis__ conjunction, a halfβchair of ring B, and a
