Nice 🎉

Sir every time i try parallel computing, my command line aborts the mission, stating that the file orca_startup_mpiexec is not found. I have tried reinstalling all the orca files twice already. and have downloaded Microsoft MPI, but this error continues. Can Someone please help. Thank you.

Perfect! Thank you so much for this video, excellent explanation. Help me a lot!

Good video 👍 Can I use the B3LYP functional together with the RIJCOSX?

Does this apply to type 3 DES?

Thank you for this! You helped me a lot. I've been confused with my homework. Now i get it.

Hello sir , Recently i have found interest in computational chemistry since our chemistry professor introduced us to IQ-Mol , which was aa relatively easy app to download and run . Orca is relatively more tedious to download and run on windows , i have downloaded (Orca 6.0.0 installer), extracted, set the path variables(C:\orca) and then tried to run the app , but it i'snt opening , the app opens for a split second and closes on its own . Can you please suggest any solution to this? thanks.

Something I didn't realize, and that isn't mentioned in most places I looked - the default installation of Orca does not include the files for parallel calculations. You have to install through the custom installation. It took me ages to figure this out!

hello sir, I got an error 911 when I did the tests with 4 cores. Can you please help me out!

Good explanation

How does one determine the abundance of an isotope?

Sir can i get ir spectra of compound I created

Thanks. Very informative

Its a very useful video. But in my case such a beautiful energy plot is not observed rather it is showing only one single dot at energy plot diagram,how to get the series of those energy points as seen in wxMacMolPlt?Shall I need to put $IPRINT command in the input file?

I didn't understand why (0+,0-) is a 1G for exemple. It's ML is equal zero, why does it be a G?

Why this new version wxMacMolPlt_x64_7.7.3msi not open after downloaded?

How to calculate madelung constant for CsCl??

Why oxygen is 13

What does 8 mean in rungms.bat mathane.inp 2022. R2. Intel 8 mathane.log？

And also another question how do you draw such beautiful MO diagrams I mean which program do you use? I also need to create some MO diagrams for an article and I am a freshman PhD student and I never got a good answer.

With which program do you draw your 3d molecules in the slides? it looks very modern I want to know.

Brilliant demonstration! thank you sir

Hello, Prof Adam. Thanks for the insightful video. I am new to Computational chemistry and so I want to ask if orca can perform geometry optimization of molecules having 43 atoms and for how long will it take to produce the output file. I have 2 molecules that I wish to run on orca. Thank you.

good stuff, thanks

what are the names you are giving to the atoms, catine and anines or something? I don't recognise these terms (I am studying properties of matter for my undergraduate physics degree so I don't know a lot of chemistry)

Is kind of weird that avogadro 1 and 2 (on windows) are able to real .out files comming from linux orca calculations, but not for windows orca calculations

This was a great video. Content creators would benefit from putting "American" as a tag somewhere in their video. I'm sick of sorting through Indian people presenting the information in broken English. I'm forced to resort to putting "American" in my search query. ...I would suggest putting English, but that wouldn't filter out the unintelligible babble from most of the available videos.

Very helpful, thank you!

This video is really good, but I wish the s and p orbitals were labeled too. I haven't gotten to connecting the Mulliken symbols yet. However, it has helped me visualize the building of MO diagrams much better. Thank you for this.

Is there a reason that the Windows distribution is 20 times larger than on Mac and comes I. Three separate parts? This is causing a headache when trying to get it working for educational purposes.

4:32 but... that's on just a single PC. Can orca be run across nodes, like how bitcoins are mined? There isn't much I can find to configure the MyMol.nodes in the working orca directory to be included with the INPUT file. I am looking how to run orca input file across multiple nodes not on a single desktop.

Can i make DES by using Cr(so4)2.6H2O and urea????

What is ca

Thank you! These are really great videos.

its says like page is not working when ever i try to register . please help me

It works beautifully! Thank you so much!

Hi sir I am studying class 8 can you make a video about "Ionic product of water and pH"

hi how do I change bond distance in every claculation ??

Chal chal tu apne mein tujhe pechanlunga

Very clear! Thank you!

Fantastic video

thanks for this video Professor! it has been very helpful

Old video so I know it's a long shot, but how do you go from 1.52 * 10 ^ 6 to 6.56 * 10 ^ 7? I can't figure out what step I'm missing

nestdude loves your video NESTDUDE HAPPY

Thanks professor for such an amazing explanation, hmm i want to ask if i want to get the energies corresponding to the MOs which tool i can use?

Thank you for the explanation! Your videos are very well done

it works! you are the best.
