THANK YOU
Thanks for clearly pointing out how to use the diagrams
THANK U
It is IIT JEE ADVANCE 2023 (Paper 2) Question
hexachloroferrate doesn't have an inversion center... you made me fail chemistry now im homeless :(
Thank you!
What would this look like if the Fluorine had a nonbonding orbital directly across from 2s..?
This was so helpful, thank you!
You are amazing. Thank you!
how to give atom no for both specifically as input and get distance
Awesome video!
Very handy!
Helpful! I am working on iridium complexes and didn't know such large complexes could be modelled with WebMO
thank you! this was super helpful.
Ok, I understand the concept of stokes law/shift. Is there an inverse for the law? If we expose a piece of tissue to a light in the visible range, can we ever create an excitation to show in the UV range? I work in Ophthalmic Photography, we use stokes law in performing fluorescein angiography, and indocyanine green angiography. I'm trying to see if I can justify exploring into visible light exposing UV reflectance or excitation with the retina. We don't want to hit the retina with UV, but if we could find it's emitting it as reflectance or excitation, we'd be breaking new ground in ophthalmic imaging.
The challenge in excitation in the visible range to give a response in the UV range is that the UV range requires more energy. If we excite a molecule using photons in the the blue light region, the excited electrons will not have the potential energy required to release a photon at higher energy (the UV region). For fluorescence to occur, you have to start the excited electron at a higher energy state compared to the wavelength of light that you want to be released for the fluorescence. There are approaches to exciting an electron to a higher energy state by using two low energy photons in rapid succession (we're talking femtoseconds between excitations) that can use lower energy light, which is the field of two photon microscopy (en.wikipedia.org/wiki/Two-photon_excitation_microscopy).
hi, why would we expect the orbitals to be like nitrogen? I thought we were taking the average of atomic numbers Zavg=8 so we have sigma 2p before pi 2p?
Je crois que le fluor est toujours monovalent il ne peut pas formé plus que d'une seule liaison !!!?
Why the (eg) 2s MO orbital of the F can contain 4 electrons?
Eg orbitals are a set of two degenerate (same energy) orbitals. Each orbital can contain two electrons, so the Eg set of MO orbitals will contain four electrons in total.
Why are 2 symmetry planes vertical and 2 dihedral? I was under the impression that a dihedral plane is a vertical plane that bisects the angle between two C2 axes, so wouldn't all 4 vertical planes follow this definition? How can someone distinguish between them?
Thank you!
Is there a way to align based on only a particular region? say I want to align based only on a folded domain of a.a. 100-130 ?
Did you figure out how to do this?
Can I please get an explanation on how you got the value of R to be 8.314. Thank you very much.
It is the universal gas constant.
Thank you so much I have a test tmrw and this was a very succinct and helpful video that is probably gonna be the reason I pass
Thank you very much, you are amazing :)
Your video helped me a lot. Thank you.
I like how I went to my professors office hours and had many lectures and still got nowhere, I understood more in a 6 min youtube video, great video, I guess Elon is right, you can learn anything on the internet.
Hi, where would your video be for running orca using cygwin?
this makes no sense why would you not just add 4H2O
The equation wouldn't be balanced in that case as whole numbers.
You've saved my life, I spent all day stressing about this question in my homework and now I FINALLY UNDERSTAND
Hi eric Can you do a video on the installation?
I didn't do the installation of WebMO, that was my university's IT department since we used the universities servers.
how did you know that it was a C3 axis
7:30
How do you know the number for the axis like C3 and C2? I'm lost on that point
Superb explanation sir thank you 🙂
this was very good keep it up Mr Victor
Hi, this is more reliable than RI approximations for larger systems?
Going to be honest and say that I'm not entirely sure. I just see the RIJCOSX approximation used often in papers focused on transition metal complexes.
Thank you
Jesus Christ of Nazareth YHVH the Living God loves you

Very helpful! Thanks!
Thank you for the nice Video, do you have a solution how to deal with Orca 5.0.3 already ? Since the MS-MPI does unfortunately not work anymore for that version of Orca Im afraid. :)
Nevermind, I found out I didnt have the latest version of MS-MPI
@@n4sty_m3l0n i'm using 5.0.3 and i have to specify the executable, and set the MS-MPI directory to Path
Why the 2p sigma is higher than 2p pai? I saw it was 2p sigma under the 2p pai in other videos
Thank you, sir
Thank you. Easier to understand with your graph!
I can understand all the steps but couldn't remember it🤣
No need to remember
Thank you for explaining everything so well
A pH 8.0 solution of magnesium carbonate is saturated with MgCO3. What is the [Mg2+]? Ksp for MgCO3 = 3.5 x 10-8 and for H2CO3 K1 = 4.6 x 10-7 and K2 = 4.4 x 10-11 . (a) 2.9 x 10-3 molar (b) 1.9 x 10-4 molar (c) 7.7 x 10-6 molar How to do this?
This video was extremely helpful and informative, thank you
Great job. Thanks👍
Concise and helpful, thank you
Thank you very much for your video. Didn't get it in my lectures, so you basically saved my life :)
