Spartan is molecular modeling and computational chemistry software from Wavefunction. It is used to create molecular models and for chemistry education.
A SPINPUT file contains the settings needed for a Spartan job.
The file is associated with the Microsoft Windows version of Spartan.
Open a .spinput file with Spartan on Microsoft Windows. If the file is not associated with Spartan, start the program and use its Open command, or select Spartan as the application for the file.
There is no standard conversion that turns a Spartan job file into another useful document format. Open the file in Spartan to run or inspect the job.
If the information must be used elsewhere, use Spartan's available export options for the resulting molecular model or calculation data rather than converting the .spinput file directly.
