Hi, I'm confused once again about a spin problem. The nuclei in a hydrogen molecule are identical protons. Spin states can be ortho (triplets) with parallel spin or para (singlets) with antiparallel spin. What are the three lowest energies for the para and ortho hydrogen molecules...

Can we split the molecule yet>? I don't mean to spilt the atom causing a nuetron to become free, but cause a molecule chain reaction...>?

Consider the molecule CN, which may be described by a dumbbell consisting of two masses M_1 and M_2 attached by a rigid rod of length a. The dumbbell rotates in a plane about an axis going through the center of mass and perpendicular to it. Write down the Hamiltonian that describes the...

4. Demonstrate concept of hybirdization using the molecule H2CO3. Show electron configuration, hybird orbitals, hybird orbitals, a complete diagram, and sigma and pi bond (if any)

I posted this in the chemistry section, but I was recommended up here. We have a molecule with three unbonded electon pairs, so they will repel each other as much as possible. That's easy, it's 360º/3 = 120º However, when we have four unbonded electron pairs the angle is 109.5º How? I...

Hello, I have a molecule soluble in chloroform. I've tried to learn its pureness with thin lead chromatography on silica gel. After several tries, I've discovered that my molecule is best eluted with 9:1 CHCl3:MeOH (for now). I am not satisfied with the elution, the molecule does not advance...

Okay I am lost. My Professor has given me the formula ( C4 H8 Br2) and the signals 3.8(s, 2H) and 1.8(s, 6H). How the hell am I suppose to compose a molecule from that?? Any ideas? :biggrin:

This is a thought experiment question. I have three air molecules. Two have the same speed. The third is faster than the other two. When they slam against each other, they keep their previous speed after the rebounding acceleration. I put them in a container. I hold them from wanting to...

What is the most complex extraterrestrial molecule yet discovered?

basic atom & molecule physics After 30 views, I hadn't received any replies to this thread as posted in the "atoms" forum. Perhaps someone here can help me out. Thanks, Glenn 1. Why exactly does a covalent bond work? I understand how the electrons fill up the shells and so forth...

1. Why exactly does a covalent bond work? I understand how the electrons fill up the shells and so forth, but why does it work. Is the bond caused by the two atoms "competing" for the same electron that pulls them together? Is that a correct analogy? 2. Are electrons EXACTLY the same...

Here is the problem: A diatomic gas molecule consists of two atoms of mass m separated by a fixed distance d rotating about an axis as shown. Assuming that its angular momentum is quantized just as in the Bohr atom, determine a) the quantized angular speed, b) the quantized rotational energy...
