Introducing Version 8.0 of
ACD/ChemSketch Freeware
Join the 500,000 individuals around
the world who are using the most intuitive chemical drawing
software available!
ACD/Labs has long been committed to helping the academic
community provide future scientists with access to software
that many will use throughout their chemistry careers. The
state-of-the-art chemical drawing software, ACD/ChemSketch, is
provided freely to students to initiate them into the world of
chemical structure drawing, nomenclature, and property
prediction at a high-level.
Over the years, ACD/ChemSketch has become the accepted
interface into the industry's best NMR and molecular property
predictions, nomenclature, and analytical data management
software. It is particularly renowned for its superior organic
structure support, and is also showing an ever-growing group
of followers in inorganic and polymer chemistry.
This software package is well suited to illustrate a
variety of chemical concepts, and includes powerful
optimization and 3D visualization tools as well as numerous
chemical templates. Drawing molecules, reactions, and
schematic diagrams never was so easy; Generate accurate IUPAC
names, or also calculate physicochemical properties for the
molecules you drew. Produce professional reports, scientific
posters, presentations, or publication-quality figures.
Chemists, researchers, publishers, and teachers everywhere
have come to rely on ChemSketch to easily and rapidly
illustrate their chemistry concepts.
To date, over 150 academic institutions worldwide have
chosen ACD/ChemSketch as their standard chemical drawing
package, and hundreds of thousands of students and professors
have downloaded the freeware version. Now, ACD/Labs has
updated the popular freeware version to match many of the
features present in commercial version 8.0, which delivers
extended capabilities for chemical structure representation of
both inorganics and polymers. See for yourself what great new
capabilities version 8.0 has to offer over version 5.0,
including:
 Polymers - Denote
repeating units within a drawn structure.
 Markush Bond - Denote
the variability in position of a substituent within a
structure.
 Labeling of Reaction
Arrows - A tool which simplifies the adding and editing
of specific experimental conditions on reaction arrows.
 Atom-Atom Mapping -
Associate atoms in reactant-to-product schemes. Users can
export mapped mechanisms into reaction-supportive formats
(i.e. RXN). Users also have the added functionality of
adding mapped reactions into an ACD/ChemFolder database.
This tool allows you to map a drawn reaction either manually
or automatically.
 Pseudo Atom - A tool
which replaces any atom in a structure with an empty atom to
create open-ended polymers and bent bonds.
- Add Explicit Hydrogens - New command on the
Tools menu.
- CTRL+dragging with either of the
 Draw Normal/Draw
Continuous/Draw Chains tool - Allows the user to draw
polymers where the components are attached at an angle of
180 degrees to each other.
- CTRL+
 Delete tool - Allows
the user to retain single atoms in a structure after
deletion.
- Draw catalytic cycles, reaction schemes and mechanisms
using fixed-angle arcs and curved arrows.
- Construct organometallic molecules with several
coordination bond styles.
- Build an extensive range of organic and inorganic
structures using specialty bond types, including:
- Delocalized and aromatic bonds;
- Double bonds with undefined configuration;
- Hollow wedge bonds;
- Quadruple bonds;
- And several more.
- Draw delocalized structures such as ferrocenes, p-allyl
complexes, and reaction intermediates, and interpret them as
chemical objects. For example:
- Retrieve General, NMR, and Mass data from an expanded
Periodic Table of Elements that includes additional elements
up to Darmstadtium.
- Calculate and display nominal mass/monoisotopic/average
mass for a fragment of a structure using the MassSpec
Scissors command.
- Support new import/export formats, including the MDL
extended (V3000) molfile format.
- Simplify document editing by previewing up to 10,000
pages in Print Preview; insert new pages and change the page
order of reports.
General modifications to the interface in version 8.0
further simplify your tasks by making it possible to:
- Customize and choose the buttons for your toolbar.
- Customize the list of properties you need to calculate
for the structure of your choice.
- Send the contents of the current page by email using the
Send command on the Options menu.
- Draw and modify tables in your document using the New
Table object and Table drawing tools. Create tables,
edit data, change the size of columns and rows, and insert
and remove any object to and from the table cells.
- Drag-and-Drop or use the Group and Ungroup buttons to
move objects in and out of a Table. Use the Protect
Content table option to disable insertion or removal of
objects.
Improvements have also been made to ACD/3D Viewer since
version 5.0. A new button  on the General toolbar of
ChemSketch now starts 3D Viewer and automatically passes the
drawn structure along. Other enhancements include:
- Support of Hydrogen to Xenon atoms;
- Additional configurations: trigonal bipyramid and flat
square;
- Improved 3D optimization of 2D structures with chiral
centers, and the option to invert the configuration of the
chiral centers;
- Ability to modify the conformation of a chemical
structure by manually changing bond and torsion angles, as
well as distances;
- Structure representation in perspective;
- Ability to resize, move, and 2D-rotate the 3D structure.
Install version 8.0 today to take advantage of the great
features ChemSketch freeware has to offer, and to gain a sneak
peak at other exciting capabilities only available in the
commercial version! See www.acdlabs.com/chemsketch
