1,1'-diethyl-2,2'-carbocyanine(+) HOMO, LUMO, Electrostatic Potential, and Partial Atomic Charges


The button “HOMO” displays the HOMO of the molecule.
The HOMO is the highest occupied molecular orbital that shows the anti bonding orbitals that are present in the molecule.
The button “LUMO” displays the LUMO of the molecule.
The LUMO is the lowest unoccupied molecular orbital that shows the anti bonding orbitals that show the shape of where the electrons will most likely occupy.
The button “Electrostatic Potential and Partial Atomic Charges” displays the Electrostatic Potential and Partial Atomic Charges of the molecule.
The partial atomic charges show the actual calculated charges that each atom contributes to the charge of the atom. the electrostatic potential field shows where the density of electrons is the highest and lowest. Red being very dense and the cooler colors being less dense.

The IR spectrum of this molecule is shown below:

The Dipole Moments of the two basis sets are shown below:

6-31G    0.614472
CCD      0.411464

Where the reason it varied so much from basis set to basis set is because as the molecule gets more and more optimized the predicted dipole moment gets more and more accurate.
