## Q1: Linear chain of three quantum wells

Problem 15.1 from McIntyre.

## Q2: Linear chain with more than three quantum wells

Problem 15.2 from McIntyre.

*Note: You will not see patterns if you express the eigenvalues in complicated combinations of sqrt(2), sqrt(3) etc. I suggest expressing the eigenvalues in decimal representation (3 significant figures).*

## Q3: Lowest three one-electron eigenstates of CO2

Problem 15.3 from McIntyre.
