Diffraction Diagram

 

Fig.1 Diffraction pattern from a well oriented fiber of the sodium salt of RMDP17 kept at 75% relative humidity shows moderate polycrystallinity. The fiber is slightly tilted towards the incident X-ray beam (Cu Kα radiation, wavelength 1.5418 Å). The calcite ring corresponds to d-spacing 3.035 Å.
