A Bragg crystal spectrometer using cylindrically curved crystals is designed to focus a divergent X-ray beam. The spectral resolution and precision of focus is determined by the quality of the concavely curved crystal. The analysis of the quality of the crystal was done using a triplecrystal X-ray s
## Abstract The singleβcrystal Xβray structures of speciophylline, mitraphylline, and rhynchophylline, oxindole alkaloids from the Peruvian climbing vine __Uncaria tomentosa__ (Rubiaceae), were determined. The three compounds show Nβ β β Hο£ΏN hydrogen bonding, which has not been observed in the crystal
