Problem P11F.7

Assume that the states of the $$\pi$$ electrons of a conjugated molecule can be approximated by the wavefunctions of a particle in a one-dimensional box, and that the magnitude of the dipole moment can be related to the displacement along this length by $$\mu=-e x$$. Show that the transition probability for the transition n = 1 → n = 2 is non-zero, whereas that for n = 1 → n = 3 is zero. Hints: The following relation will be useful: sin x sin $$y=\frac{1}{2} \cos (x-y)$$ − $$\frac{1}{2} \cos (x+y)$$. Relevant integrals are given in the Resource section.

GENERAL CHEMISTRY I – DR. STREIT Week of February 21, 2016 February 23, 2016 Ionic Bonding  Electrostatic attraction that holds oppositely charged ions together in an ionic compound (salts) o Transfer of electrons o Generally a metal with a nonmetal o Gain or lose electrons to fill an octet o Form large crystalline solids where each cation is surrounded by an anion, etc o High melting points o Do not conduct electricity in solid state  Electrons cannot flow in a rigid structure, and electricity is defined as the flow of charged particles  It does conduct in liquid or gas form because electrons are free flowing o Brittle o Mostly soluble in water o Measured with Coulomb’s law  Energy needed to dissociate ions  Lattice energy- measures ionic stability (depends on magnitudes of charge and distance)  The greater the product of charges of ions in a compound, the greater the attractive forces, therefore, the higher the melting point  The bigger the ions, the greater the distance between ions, therefore, the attractive forces are weaker thus lowering the melting point o Formation of ionic bonds releases a large amount of energy  Higher lattice energy, smaller radius o Neutral o Chemical form
