SHELXTL^TM — The Standard for Reliable Structure Solution and Refinement

SHELXTL — the extended, proprietary version of SHELX — is the heart of the APEX2 software suite. Reliable engines are developed and maintained by Prof. Sheldrick at Goettingen University. The SHELXTL package is the gold standard for structure solution and refinement in Academia and Industry.

XPREP has all tools built in for unambiguous space group assignment, statistical analysis, display of calculated Patterson sections, de-twinning of merohedral crystals, and much more. XS and XM form the core of the structure solution package. XL is the most popular refinement program, extensively tested on many thousands of structures. XP and XSHELL provide atomic and molecular graphics for interactive structure refinement and structure display.
