5) [10 marks] Complexes of formula cis-Rh(CO)(phosphine)2Cl with different phosphine ligands have different C-O stretching bands in the IR spectrum. Note that the complex cis- Rh(CO)(phosphine)2Cl has a square planar structure. a) Explain why different phosphine ligands can affect the C-O stretching bands. b) Match the infrared bands with the appropriate phosphine ligand with explanation. Phosphines: P(p-C6H4F)3, P(C6H4Me)3, P(t-Bu)3, P(C6F5)3 v(CO): 1923, 1965, 1984, 2004

A population of beetles are growing according to a linear growth model. The initial population (week 0) is $P_0 = 7$, and the population after 10 weeks is $P_{10} = 87$. Find an explicit formula for the beetle population after $n$ weeks. $P_n = $ After how many weeks will the beetle population reach 175? weeks Question Help: Video 1 Video 2

The equation describing the two-particle wave function for two identical fermions is given by $\Psi^F(x_1, x_2) = \frac{1}{\sqrt{2}}(\psi_a(x_1)\cdot\psi_b(x_2) - \psi_a(x_2)\cdot\psi_b(x_1))$. The term $\psi_a(x_2)\cdot\psi_b(x_1)$ has a negative sign, and the term $\psi_a(x_1)\cdot\psi_b(x_2)$ has a positive sign. How important is this sign convention? The sign of the exchange term is arbitrary; it could be positive or negative. But the first term must always be positive. It does not matter which term gets which sign; all that matters is that they have opposite signs. If you multiply a wave function by an overall factor of -1, you still obtain a valid wave function. Both terms can have either sign, and each of the four sign combinations (++ , -- , -+ , +-) leads to a valid wave function. These are the only signs possible for the two terms, because the second term is the exchange term and thus must have a negative sign.
