From Wikipedia

<br />
<br />


In spectroscopy, '''oscillator strength''' is a dimensionless quantity that expresses the probability of [https://en.wikipedia.org/wiki/Absorption_(electromagnetic_radiation) <u>absorption</u>] or [https://en.wikipedia.org/wiki/Emission_spectrum <u>emission</u>] of [https://en.wikipedia.org/wiki/Electromagnetic_radiation <u>electromagnetic radiation</u>] in transitions between [https://en.wikipedia.org/wiki/Energy_level <u>energy levels</u>] of an atom or molecule<sup>[</sup>[https://en.wikipedia.org/wiki/Wikipedia:Accuracy_dispute#Disputed_statement <sup>''<u>dubious</u>''</sup>]<sup>'' – ''</sup>[https://en.wikipedia.org/wiki/Talk:Oscillator_strength#Wrong_definition_oscillator_strength <sup>''<u>discuss</u>''</sup>]<sup>]</sup>.<sup><u>[https://en.wikipedia.org/wiki/Oscillator_strength#cite_note-Demtr%C3%B6der2003-1 [1]][https://en.wikipedia.org/wiki/Oscillator_strength#cite_note-Robinson1996-2 [2]]</u></sup> The oscillator strength can be thought of as the ratio between the quantum mechanical transition rate and the classical absorption/emission rate of a single electron oscillator with the same frequency as the transition.

To literally line up DOS and STATES, you may need to type in 0 for both fermi and alpha+beta.

<br />A more standard way is to use the middle point energy between HOMO and LUMO i.e. (E_HOMO+E_LUMO)/2 for fermi and 0 for alpha+beta. In this way, the mid point of DOS is at zero, anything below zero is occupied and above zero is unoccupied.

I am initially specifying a style that I will be using. In this case chose style 4 and am editing it to what I want.

lw stands for linwidth, lc line color, not sure where the library is but lc -1 is black, 0=red I think and find out other through trial and error

lw is just multiplyer, so lw 4 is 4 times larger than default.

unset key gets rid of key,

[#,#] is the range of my x axis graph.

($#-###): $# is the column I want to take data from which is being subtracted by the amount of shift I am giving to the data (we want data to be centered at 0 sometimes and so for DOS we take the middle between the start of non occupied plus the end of occupied and divide by 2 to get our shift. (Notoccupied + occupied)/2 ) and the number after the “:” is the column I am correlating the X and Y axis with. So when we plot stuff we need to specify what is the x and what is the y axis.

not sure exactly what the “w i” portion does but it helps us change from points to lines and then is what fills in the red portion of our graph. (The “i” stands for impulses. Add an extra “lw 2’ to increase the line width as shown in green text.) “w l” does the same thing but DOESN”T fill out the the electron density portion.

xlabel and y labels are the axis titles and offsets help position them due to the changing sizes of the axes and tics.

Tics are the numbers on the Y and x axis so ytics offsets them and xtics does the horizontal axis change.

Kilins Guidance to make PARCHG files… I think

Dear Meade,

below are steps I did for creating orbitals files on nersc.

I will let you know when they are ready and instruct on how to visualize.

slides are good, under given limits.

In the given time, you may add conclusions as you see them..

Best wishes,

Dmitri

Submitted batch job 32413471

many thanks for the new version!

The main question in your email is orbitals with VASP:

a. generate or use premade healthy WAVECAR 

(it is an analog of .chk in gaussian)

b. in a new directory, use template of the INCAR for orbitals and run vasp once again.

the templates are named ~/bin/INCAR/INCAR_pc  and similar names.

(it is an analog of the cubegen procedure in gaussian)

c. upon successful run, there appear files nammed PARCHG.XXXX.ALLK, where XXXX stands for the index of orbital, e.g. PARCHG..01112.ALLK

(those files are analogs of the .cube files in gaussian. note that vasp DOES not generate literal .cube files!)

d. download these files and open then in the VMD - the same software you have used for the trajectories.

I will have a look on the slides and let you nko if any quicl changes are needed or we can go ahead with this version

Best wishes,

Dmitri

| Step 2. Changing PARCHG Files to cube files (For Orbital Visualization)
| From what I have seen we need cube files to show in guassview AND VMD
|-
| Once obtained PARCH.####.ALLK Files then use following command in PHOTON to convert the orbitals you care about to cube!
| <br />
|-
| ~/vtstools/chg2cube.pl filename
| <br />
|-
| 3
| selecting PARCHG
|-
| 1 6 7 8
| (These are the atomic numbers for the atoms in your system. In my case I have Hydrogen, Nitrogen, Oxygen, and Carbon
|-
| Your cube file is then generated
| <br />
|-
| SEND cube files, POSCAR (OR CONTCAR), CHGCAR FILES TO DESKTOP
| <br />
|-
| Step 3. Using VMD to generate orbitals
| <br />
|-
| Open VMD
| <br />
|-
|
In the VMD Main window go to “File” “new Molecule” Upload your

1.POSCAR (OR POSSIBLY CONTCAR): By selecting VASP_POSCAR under the “Determine file type:”

2. CHGCAR: By selecting VASP_CHGCAR under the “Determine file type:”

3. USE THIS ONE PARCHG: By selecting VASP_PARCHG under the “Determine file type:” (Even though the file ends in .cube we are classifying it as PARCHG)

| <br />
| [[File:VASP_VMD_LAMMPS_CCAST_LINUX_HTML_eae9e77b87b8627b.png|222x103px]]
|-
|
After all three are uploaded,

in the VMD Main window go to “Graphics” and then “Representations”
| <br />
|-
|
In the Graphical Representations window follow these three examples.

<br />(Change the file you are using by the dropdown menu of “selected Molecule”)
|
The red lettering means that PARCHG Isosurface isn’t being shown. You can double click on the red lettering to make it black and showing on the OpenGL Display Window. Double click again to revert to black.

Parchrg can be shown and can be visualized in conjungtion with the CHGCAR file

-You can change the iso value in CHGCAR to get varying orbital visualizations.

-Play with it.

-Change the color by changing the ColorID to different ones.

Change FERWE=#### to match the total number of orbitals/bands. In this example we have a total number of 160 bands/orbitals.


The first segment of FERWE, “110*1” says we have the first 110 orbitals occupied. The second portion is orbital number 111 which we have listed as a “0” signifying this orbital is unnoccopied for our job submission. Then orbital number 112 is occupied with “1”. Then orbital number 113 is unoccupied with “0”. Then orbital number 114 is occupied with “1”. The last part of “46*0” is talking about the other orbitals not mentioned. These orbital should add up to 160. These numbers change with the differing orbitals designating in the CANDIDATES FILE.

The main thing that is changing is the position of one occupied orbital and one unoccupied orbital when the compound is in ground state. In this example number 111 is usually occupied in ground state and we are moving the electron to 114 which is unoccupied in ground state.

input_ANA should have similar format to this

Where the first 3 numbers are from POSCAR, the last 3 are the number of cells in the x,y,z axes respectively. This files was duplicated across Z axis.

Go into the directory with the shot files with the multiple cells. Make sure that some files have this comment inside of them by opening a shot file that has name shot##n#.xyz

The comment should be.

finds lines that have both “created by duplicating cells” and the number 17 in the same line.

17 is the mass number we are looking for

I am unsure what the “.*” does in this code

make sure there is a space between the * and the 17
