6) This question is concerned with vibrational spectra (Infrared and Raman). a) How many normal modes of vibration are expected in these molecules? (Show calculations) i) Theobromine (the caffeine-like stimulant that is found in chocolate) b) In the molecular vibration shown here for trans-1,4-dichlorocyclohexane, both chlorine atoms stretch away from the carbon to which they are bonded (arrows). Will this mode be IR active? Will this mode be Raman active? In each case, why or why not? ii) Cyanopolyyne (an organic molecular wire that has been detected spectroscopically in interstellar space, and is postulated to be a precursor to biomolecules: HC=C-C=C-C=N c) Why are CH4 and CO₂ considered greenhouse gases, but O₂ and N₂ are not? d) Are the vibrations shown here a degenerate pair (Yes/No)?

(a) The ionization energy of molecular hydrogen (H2) is greater than that of atomic hydrogen (H), but that of molecular oxygen (O2) is lower than that of atomic oxygen (O). Explain. (Hint: Think about the stability of the molecular ion that forms in relation to bonding and antibonding electrons.) (b) What prediction would you make for the relative ion- ization energies of atomic and molecular fluorine (F and F2)?
2. According to the Beer-Lambert law absorbance is proportional to concentration at each wavelength. In principle, one could choose any wavelength for quantitative estimations of concentration. However, we generally select the wavelength of maximum absorbance for a given sample and use it in our absorbance measurements. Especially, one should avoid the steep portions of the spectrum. Why? 3. Which concentration range a dilute or a concentrated one - is chosen for accurate determinations of unknown concentrations?
Q.1: The force constant of the bond in HCl is (516 N/m). Assuming the value of the force constant does not depend on the mass of the atoms in the molecule, calculate the fundamental vibrational frequency of each of the following: 'HCl. 'H'Cl and ?H*Cl. Q.2: The Interatomic Distance in the HCl Molecule The spacing, A(1 /2) between the lines in the rotational spectrum of HCI(g) is 20cm'.Calculate the distance between the nuclei (the length of the bond) in the HCl molecule.
In infrared spectroscopy, the following carbon-hydrogen bonds have peaks at different wave numbers. Explain why this is the case
The properties of a molecule that are most frequently calculated are geometry, energy (compared to that of other isomers), and spectra. Why is it more of a challenge to calculate “simple” properties like melting point and density? Hint: is there a difference between a molecule X and the substance X?

The unsaturation number or degree of unsaturation (U) can be used to determine the number of rings and multiple bonds in a compound from its molecular formula. Given a structure, you can determine the number of hydrogens without having to count them explicitly. Consider three compounds and their degree of unsaturation. (a) A compound A has the molecular formula C7H13ClN2OC7⁢H13⁢ClN2O. How many rings and/or π bonds does it contain?
Select the bonds in the 3D representation of methyl urethane below that are multiple bonds. (Hint: Consider the number of bonds attached to an atom in the image compared to the normal valence of that atom.
