LinMOPAC 1.0 provides a simple graphical user interface (GUI) to the semiempirical computational chemistry program MOPAC2000 version 1.33. 3D molecular visualization and a simple MOPAC setup dialog make running experiments easy even for inexperienced MOPAC users:

• LinMOPAC reads and displays molecular structures from standard MOPAC ".dat" files.
• It provides visual controls for running a MOPAC job.
• LinMOPAC displays the final molecular geometry and molecular orbitals as well as the text MOPAC output file.
• Visual rendering modes allow for wire-frame, ball-and-stick, cylinders, and space-filling molecular structure representations.
• Input files can be edited in text mode.
• No knowledge of MOPAC keywords is required to run LinMOPAC.
• The orbitals can be displayed using different surface representation methods in both opaque and transparent models.
