You can easily build up 2D molecules in the Molecule
Window of MolWorks by using a mouse. You can also build up reasonable 3D
molecules using the clean-up function and can change the atomic symbol and
the bond order.
MolWorks has the capability to estimate the properties
of the molecules based on "Group Contribution Method ( Joback method )" and
"Principle of Corresponding States".
Based on estimated properties of pure components, you
can apply the PVT diagram of not only pure component but also mixtures. You
can simulate any ratio of 2 pure components.
