Bruker small molecule crystallography

Y Cerenius, K Ståhl, L A Svensson, T Ursby, A Oskarsson, J Albertsson, A Liljas
A new X-ray crystallographic beamline is operational at the MAX II synchrotron in Lund. The beamline has been in regular use since August 1998 and is used both for macro- and small molecule diffraction as well as powder diffraction experiments. The radiation source is a 1.8 T multipole wiggler. The beam is focused vertically by a bendable mirror and horizontally by an asymmetrically cut Si(111) monochromator. The wavelength range is 0.8-1.55 A with a measured flux at 1 A of more than 10(11) photons s(-1) in 0...

Detailed vibrational studies (FTIR and Raman on powder samples, polarized FTIR microscope on a small single crystal, polarized FTIR using Bruker reflection unit on a single crystal and polarized Raman) have been carried out. Vibrational spectra are discussed in relation to the crystal structure published previously. In this crystal a network of hydrogen bonds link water molecules, guanidinium cations and hydrogenphosphate ions. The 13 different hydrogen bonds in G2HP crystal structure are detected. On the basis of detailed vibrational studies the detailed assignment of observed bands was made...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
