DFT Modules

What kind of data do you need?

Density Functional Theory (DFT) aims to obtain the ground-state electronic state of materials.
Get information about ground-state energy, interatomic features of the optimized structure and other electronical properties of materials.

Molecular Orbital Surfaces

You can visualize the molecular orbital of the molecule.

To get molecular orbital surfaces in MatSQ ⇢

Atomic Analysis

Analyze the calculation results, the molecule geometry obtained after optimization, charge information, and bond order.

To analyze the (inter-)atomic properties in MatSQ ⇢

Vibrational Frequency

You can get the vibrational frequency for the molecule. You can figure the IR, Raman spectrum, and animate the normal mode.
