Calculate the wavelength difference between the second lines in
the visible regions of the hydrogen spectra of (Deuterium) and
(Tritium) isotopes. (mass of deuterium and tritium nuclei is
approximately 2 and 3 times the mass of hydrogen nuclei,
respectively. mass of the hydrogen nucleus is also 1836 times mass
of the electron)?
Calculate the vibrational energy difference, in cm-1, between
the v=0 and v=1 energy level in a hydrogen chloride-35 molecule.
Isotope masses to three decimal places are taken from NIST and
force constants from hyperphysics. Use the isotope mass, not the
average mass.

(b) [5 marks] Calculate the energy difference between the
photopeak and the Compton edge.
(c) [5 marks] Calculate the position of the backscatter
peak.
Using a molecular mechanics program, calculate the energy
difference or the difference in heats of formation between Z- and
E-stilbene. How do your computed values compare to the difference
in heats of hydrogenation of the two isomers.

Calculate the energy difference for a transition in the Paschen
series for a transition from the higher energy shell n=6. Express
your answer to four significant figures and include the appropriate
units
Calculate the energy difference for a transition in the Paschen
series for a transition from the higher energy shell n=5.
Express your answer to four significant figures and include the
appropriate units.
Pauling's electronegativity scale accounts for the difference in
energy between the heteroatomic dissociation energy and the half
the sum of the homoatomic dossiciation energies (This difference is
converted to eV and the square root is taken to get the difference
in electronegativities). Fluorine is arbitrarily given an
electronegativity value of 4 and the rest are derived from there.
This experimentally derived parameter tells us about the ionic
contribution to a bonding interaction. Values are not given for the
Noble Gases....
