From a rudimentary analysis of the pattern of keys pressed, I think "grmpi g" was meant to be "helping". However, it may also have been a Pokemon reference, I am not sure.
This Jahn-Teller question is going to be the death of me. I knew I wouldn't be able to sleep without figuring it out, but figuring it out meant that I didn't get to sleep anyway.
@heather You may want to focus your efforts somewhere else. Move on and ignore. This question is going to disappear soon and so is your effort. While you have done a very nice job, it sadly will turn into thin air soon.
if I do population analysis on some molecule with a different basis set, I get more virtual MO's. Do you know what is the exact relationship between the basis set I use and the number of MOs it's going to spit out?
A basis set in theoretical and computational chemistry is a set of functions (called basis functions) that is used to represent the electronic wave function in the Hartree–Fock method or density-functional theory in order to turn the partial differential equations of the model into algebraic equations suitable for efficient implementation on a computer.
The use of basis sets is equivalent to the use of an approximate resolution of the identity. The single-particle states (molecular orbitals) are then expressed as linear combinations of the basis functions.
The basis set can either be composed of...
Werner Karl Heisenberg (German: [ˈhaɪzənbɛɐ̯k]; 5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, this matrix formulation of quantum mechanics was substantially elaborated. In 1927 he published his uncertainty principle, upon which he built his philosophy and for which he is best known. Heisenberg was awarded the Nobel Prize in Physics for 1932 "for the creation of quantum mechanics...

During my ventures in cleaning, I came across another phenomenon of quasi-dead questions, that won't get cleaned up, but (most) are essentially noise. There are a few (currently 227) questions which have a positive score, but are closed (excluding duplicates) and no-one "answered" them before the...
I have a 6000 gallon aluminum tank that has about 250 gallons of corn syrup in it. It's about 35F outside and I don't have a very efficient way of heating the tank. Corn syrup is extremely viscous at this temperature. I need to remove the syrup from the tank. I have access to cold water, but not ...

I am officially changing the post to a tag-blacklist-request.
I think, and so far there was no objection, that it is a meta-tag, and that it is not helpful. Unlike homework or reference-request it basically only serves as a placeholder. I would say it is on par (maybe a tiny bit better) with ...
Why do colligative properties only depend on the number of particles and not the size?
My argument being that since the root cause of these properties is the occurrence of solute particles on the surface, reducing the vapour pressure of the solvent, shouldn't bigger molecules such as urea, give ...
Please. PLEASE pay attention to the tags you're creating. You've been creating a lot of typo-y and wrong tags lately, and they've been a pain to clean. Don't edit, and take a second look at the tags on your questions. — M.A.R.8 secs ago
In a recent exam, I came across this question.
A dry air is passed through the solution,
containing the 10 g of solute and 90 g of
water and then it pass through pure water.
There is the depression in weight of
solution it by 2.5 g and in weight of pure
solvent by 0.05 g. Calculate ...
I have no idea how to do this, its due tonight at 12... Thanks!
The final step in manufacture of pure platinum (for use in automobile catalytic converters and other purposes) is the decomposition reaction of (NH4)2PtCl6. In addition to the solid metal, the following gaseous byproducts are also f...
Right now, I guess we don't have that many chromatography questions, let alone TLC. However, if in the future we decide that it's a good idea to split chromatography up into its subsets, then TLC can't be a synonym anymore.
But to be honest, I don't know 100% how tag synonyms work. Maybe it might still be a good idea.
Hi! I'm studying a usual linear accelerator for electrons and I'm trying to get the force that corresponds to the power radiated ($P=m\tau \ddot{x}^2$). I've tried calculating the associated work which gives me $W=m\tau\int_0^T\ddot{x}^2\mathrm{d}t=\int_0^T\vec{F_r}\cdot\vec{\dot{x}}\mathrm{d}t$, how do I continue ?
That is what this site is all about.
Plus you could answer it yourself and get more points :P
