When objects are hovered, pressing the comma key will open that object’s visual specifications formatting window. When bonds are hovered, the arrow keys will orient the bond in the pressed direction from start atom to end atom, rotating the entire molecule it is contained in. Opening a previously typed atom label will set the enter key text to that label. When atoms are hovered, the enter key will now set the hovered atom’s label to the last typed atom label. – 13C: alkane improvements, alkene improvements, alkyne improvements, decreased quaternary peak intensities, heteroaromatics – 1H: anisotropic effects, ring strain, hydrogen bonding effects, rapid exchange, diastereocenters, heteroaromatics NMR simulation algorithms greatly improved. More restriction options have been added for the Search widget, and those options are now accessible right from the widget. Search widget now displays a drop box for placing the search structure in, replacing the spinner that was previously there and making the use of the widget much more intuitive. Access to to chemical suppliers for the chemicals drawn by clicking the Chemical Suppliers menu item in the Structure menu. Access to structures and properties provided in the MolGrabber widget. Incorporated the input and output of the MDL RDFile format for storing reaction schemes. Both V2000 and V3000 connection tables are supported Incorporated the input and output of the MDL RXNFile format for storing single reactions. Incorporated the input and output of the ACD/ChemSketch Document format. The NMR simulation algorithms have been greatly improved. Also implemented is a complete interface to the ChemExper database providing structures and properties from the MolGrabber widget and access to chemical suppliers for structures that you draw. ChemDoodle now reads and writes the formats of all chemical sketchers. Executive SummaryĬhemDoodle 3.1 provides three new file formats: ACD/ChemSketch Document, MDL RXNFile (both V2000 and V3000) and MDL RDFile. Chemdoodle hydrocarbons update#

(It is mentioned in errata, for page 310).ChemDoodle 3.1 has been released! We provide this upgrade, free of charge, to our existing customers. *) Please note there is a mistake in the example from the book, the pyridine ( 4) has wrong internal ring numbering - 4 should be replaced with 5.
Phane Nomenclature, Part II: Modification of the Degree of Hydrogenation and Substitution Derivatives of Phane Parent Hydrides. 
Phane Nomenclature, Part I: Phane Parent Names.If the numbers in the first parentheses were sorted, it would mean a different structure, that is little bit hard to draw in 2D:ġ,5(1,2,3),2,4,6,8,9(1,4),3,7(1,2)-nonabenzenabicyclononaphane
Note that the "superatom" (more precise "amplificant") locant ordering matters. It indeed can be named quite nicely using the recent "phane" nomenclature from the Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names 2013, here is the example *īy abstracting to the bicyclo phane composed of nine benzene nodes ("superatoms") of three kinds, we getġ,5(1,3,2),2,4,6,8,9(1,4),3,7(1,2)-nonabenzenabicyclononaphane
