*Harmonic vibrational frequency computation at the mp2/cc-pvdz level in serial mode: [RAW]

*Anharmonic vibrational frequency computation at the mp2/cc-pvdz level in parallel mode is given below. By selecting MODE SOW, a separate file is created for each gradient computation. Make sure the method you choose has an analytic gradient. [RAW]

*When each gradient computation is completed, you can proceed to the frequency computation by selecting MODE REAP: [RAW]

*Anharmonic vibrational frequency computation at the mp2/cc-pvdz level in parallel mode is given below. In this example the PSI4 software is employed instead of MacroQC When an external software is used, the options for the external software should be provided in the DG_EXTERNAL block. MacroQC generates all necessary input files for the allowed external software. By selecting MODE SOW, a separate file is created for each gradient computation. Make sure the method you choose has an analytic gradient. When each gradient computation is completed, you can proceed to the frequency computation by selecting MODE REAP. [RAW]

This is an example of a single-point energy computation at the LSSMF-ccsd(t)/cc-pvdz level. In this example, level 3 is used for generating bonded fragments. For this example, bonded.inp, nonbonded.inp, and groups.inp files are written. Some important information required for the REAP mode will be written to the lssmf.chk file. Make sure the lssmf.chk file is not deleted. [RAW]
