Explain why excitation and emission peaks have different wavelengths for a molecule? Is it due to different electrons going into their excited states and coming back down? In that case, the peaks should be identical? That is my answer.

Answer all parts. (a) Sketch several H20 molecules interacting in the solid phase. Briefly explain why the [6 marks] addition of NaCI lowers the melting point of H20 (b) CO2 is a molecule that is not expected to have a dipole moment. Why? Your solution [2 marks] (c) When vibrationally excited, CO2 shows a slight dipole that increases with vibrational [5 marks] should make use of simple, well-labelled diagrams. excitation. Why? Your solution should make use of simple, well-labelled diagrams...

Explain why different cells can perform different functions even though they have identical organelles
a) what effect does the change in internuclear separation in a diatomic molecule due to its vibration (the binding energy curve is asymmetric) have on the rotational energy levels of molecule? b)Explain why the separation between vibrational levels is somewhat smaller in an excited electronic state than in the ground electronic state. Explain the same effect for rotational states. c)show the ratio number of molecules in rotational level r to the number in the r=0 level, in a sample at...
for NMR Spectrum looking at a molecule we have to decide with where the protons are in the environment how many signals will show on the NMR Spectrum. I don't understand why they are saying the protons in the pink are going to all show one signal and the protons in red are going to show their own signal. To me the line of symmetry goes down the middle of the compound and they are symmetrical so they all should...
The electron density solutions for the molecule H2 in question 1 are different sizes. Why is that? Select one: Solutions for the Schrödinger equation produce different eigenstates that have variable shapes. Panel a represents the orbital when the electron spins are antiparallel and panel e represents it when they are parallel; the rest show the transition between those two extremes It is most likely that electrons will be found near the two hydrogen nuclei. Each orbital representation depicts a different...
1. Compare the structures of SO, to PF, and explain why they have different molecular shapes. (when comparing two objects, you should discuss both and mention both their similarities and differences and explain the reason for the differences) 1.

Explain why patients exhibiting cystic fibrosis should have different NPD levels than patients not exhibiting cystic fibrosis.
Artificial rubies have an atomic system consisting of three main energy levels and can be used to produce short pulses of laser light. The energies of these levels are Eo, E1 and E2, in increasing order of energy (a) Write down an expression giving the relative population of the energy levels Eo and E1 at thermal equilibrium. b) Explain what is meant by the term population inversion. Described how this is achieved in a three-level laser system Photons of wavelength...
1. If DNA polymerase III was going to attach a new nucleotide onto the DNA molecule shown to the right, where would it attach it? 2. Why are the ends labeled A and C different? a. The diagram is drawn incorrectly, they should be the same One is o pure onsa pyrimidine. c. One is a purine, one is a pyrimidine d. Double-stranded DNA is antiparallel. e. This is after DNA replication -before DNA replication, they look the same. 3....
