I guess you are using the transition state as input geometry, right? How can I calculate the Transition state on gaussian and construct the energy profile ?? Question Killed or failed jobs can be restarted, but for this checkpoint file should be generated via a %Chk command within the Gaussian input file. Gaussian weighs whether to run the calculation as a direct-SCF (memory intensive, integrals done in-core), a classical SCF (disk intensive, integrals written to file) or some hybrid calculation based upon the size of the molecule, the amount of memory available and the size of the disk space available, in order to optimize the the performance ESM_1. pdb to Hello, I am a newcomer to PSI4 and learning my way around SAPT-0 calculations using PSI4. 25 answers.

Interfacing to Gaussian. 3: Output in the form of data statements. $\begingroup$ Do you remember the postulate "The state of a quantum mechanical system is completely specified by its wavefunction"? Gaussian will find the wavefunction of your input system, which includes the location of the radical in that case (when dealing with wavefunctions, the spin density is the property you want to look at). Ever wonder what’s in some of the numerous checkpoint files you have accumulated or which checkpoint file of several is the one you want? which gives you much of the data in the form of an input file.
