No Computing Resources? No Problem! Psi4Education has partnered with ChemCompute to enable you to run Psi4Education Jupyter notebook labs using FREE compute resources through ChemCompute. Lessons 1, 4, and 5 cover all of the prerequisite skills needed. If you need resources to learn these prerequisite skills, we recommend these lessons from the Molecular Sciences Software Institute. See this page for an explanation of these prerequisites. These labs assume some prerequisite knowledge of python. Psi4Numpy allows you to import and use Psi4 functions directly in Jupyter notebooks. Many of the lab activities use Psi4Numpy, the Psi4 Python API. Installing Psi4 and Jupyter notebook Instructions for installing psi4 in a conda environment suitable for the Psi4Numpy Jupyter notebook labs. Psi4Education aims to increase students exposure to scientific programming and computational chemistry and help students learn chemistry through computation. We offer a suite of free, open-source lab activities, suitable for use in classes across the chemistry curriculum, which use Psi4, the Psi4Numpy Python API, and WebMO, a graphical front end to help build molecules and set up calculations for Psi4.

There are significant changes in corresponding bond lengths and angles and crystal packing of phenol-based diketones having OH, CH 3 or C(CH 3) 3 substituents in the para-position. The electronic spectra of I and 4-methyl-2,6-dibenzoylphenol ( mdbpH) also predicted by the B3LYP/6-31g(d) method show some blue shifts compared with their experimental data.
Comparison of the optimized geometries by means of a density functional theory molecular orbital theoretical calculation at the B3LYP/6-31g(d) level with the corresponding crystal structures gives support to these observations. The crystal packing is stabilized by weak intermolecular C–H
