Package to calculate VPT2 anharmonic frequencies.
Project description
pyVPT2
About
pyVPT2 is a package to calculate VPT2 vibrational frequencies using psi4 or qcengine. Cubic/quartic constants can be optionally computed in a distributed parallel fashion using QCFractal.
For usage check the documentation.
Disclaimer: This codebase is still under active development.
Dependencies
Required:
- psi4 = 1.8+
- python = 3.8+
Installing psi4 will pull all other required dependencies.
Optional:
- qcportal =
