Techniques and applications of quantum theory

Quantum theory, often known as quantum physics, is the foundation of modern physics and encompasses the nature and behavior of matter and energy at the atomic and molecular levels. As the exact nature and behavior of atomic and subatomic particles are impossible to determine, the laws of classical physics do not apply to this discipline. As a result, quantum field theory is primarily based on assumptions and probabilities.

Question

1. Experimental chain dimensions for poly(ethylene terephthalate) (PET) at 275°C are given by
(h*)o/M0.90 A² mol/g. Calculate C, the statistical segment length, and the persistence
length for this polymer. Based on these numbers, is PET a flexible polymer, or not? What
would you expect based on the molecular structure?

1. Calculate the Coulombic (ionic) interaction energy between atoms for the C=O ∙∙∙H-N hydrogen bond in a peptide at a distance of 1.5Å in units of kJ/mol. Assume that the partial charge on O is −0.434, the partial charge on H is +0.417 and the permittivity of the protein environment is 6. 2. The dipole moment of an individual peptide group is approximately 3.46 D. Assuming that the dipoles line up linearly estimate the energy of interaction (in kJ.mol) of the hydrogen bond in Q1 using a dipole-dipole model.

22-30. (a) The mean free path is the average distance a molecule travels before colliding with another molecule. The mean free path, A, is given by A = kT/(V20P), where k is Boltzmann’s constant, T is temperature (K), P is pressure (Pa), and o is the collision cross section. For a molecule with a diameter d, the col- lision cross section is nd. The collision cross section is the area swept out by the molecule within which it will strike any other molecule it encounters. The magnetic sector mass spectrometer is maintained at a pressure of ~103 Pa so that ions do not collide with (and deflect) one another as they travel through the mass analyzer. What is the mean free path of a molecule with a diam- eter of 1 nm at 300 K in the mass analyzer?
