Complete Structure Determination

Now Faster, Easier.

Single-crystal XRD comes of age. Of all available techniques, x-ray crystallography alone is capable of

unambiguously determining complete three-dimensional molecular structures, confirming the connectivity and

stereochemistry of molecules, and providing precise information concerning bond lengths, bond angles, and

molecular dimensions. N ico l e t ' s a d v a n c e d c r y s t a l l o g r a p h y s y s t e m s a r e

of an organic or organometallic molecule having 25 non-hydrogen atoms can typically be solved in less than a

day wi th the Nicolet R3m/E — a typical laboratory n o w solves over 100 structures per year using this system!

complete systems rapidly and simultaneously perform data collection, s tructure determination, display, and plotting of

three-dimensional structures, wi thout the need for an external computer.
