Minor improvements to JDX spectra input and much faster output to JDX format for simulated NMR spectra.Improvements to congested spiro structure layout.Significant speed improvements for generating isotopic distributions.This option is found in the Preferences window, under the Functions tab in the Stereochemistry section. The MDL/BIOVIA stereochemical drawing interpretation algorithm is now implemented along side the IUPAC specification for input drawing interpretation only (the IUPAC specification will always be used for output when using ChemDoodle functions).A new chapter 15 in the user guide focuses solely on stereochemistry discusses all of these features in detail. Assign "R", "S", "E", "Z", "M", "P" and the pseudo-asymmetric "r", "s", "e", "z", "m" and "p" descriptors with a simple menu function. al., the CENTRES library by John May is included which supports advanced and consistent CIP assignment for all stereochemical features supported by ChemDoodle. A new advanced CIP descriptor engine has been implemented.Several issues have also been corrected, described below. We believe ChemDoodle is now the industry leader for handling stereochemistry, especially in 2D drawings.
A new advanced CIP descriptor engine is implemented for the most accurate and consistent CIP assignments and the MDL/BIOVIA stereochemical drawing interpretation algorithm is now implemented along side the IUPAC specification. ChemDoodle 2D v11.13.0 is a feature update wrapping up our latest massive work on stereochemistry.
