Homework Statement
"The angular part of the wave function for the dxy orbital is (√(15/∏)/4)sin^2(θ)sin(2ϕ). Show that this expression corresponds to the dxy orbital"
Homework Equations
conversion of Cartesian to spherical coordinates:
r=√(x^2+y^2+z^2)
cosθ=z/r
tan(ϕ)=y/x
trig identity:
sin(2x)=2sinxcosx
normalization:
N^2∫ψ*ψdτ=1
dτ=r^2sinθdrdθdϕ
0≤r≤∞
0≤θ≤∏
0≤ϕ≤2∏
The Attempt at a Solution
in Cartesian coordinates dxy is represented as simply xy. I converted xy to spherical coordinates and manipulated the equation the relevant equations to get xy=(r/2)sin^2(θ)sin(2ϕ) as follows:
xy=rsincosϕrsinθsinϕ
xy=rsin^2(θ)cosϕsinϕ
xy=rsin^2(θ)sin(2ϕ)/2
Then I tried to normalize the equation, but I ended up with
∫r^3 from 0 to ∞, which goes to ∞/does not converge
and ∫sin2ϕ which equal zero.
