## Shrodinger Equation

$H_{\psi }=E_{\psi }$

1-D: $E_{TOTAL}\psi (x)=E_{k}\psi (x)+V(x)\psi(x)=-\frac{h^{2}}{8\pi ^{2}m}\frac{d^{2}\psi(x)}{dx^{2}}+V(x)\psi(x)$

### Shrodinger Equation

When do you know when to use the Shrodinger Equation? What phrases or words in a question hint towards using the formula.

If I remember correctly, we do not really need to know this. I'm pretty sure Lavelle just wanted to show us why we have it.

### Re: Shrodinger Equation

I can give you an example of the Schrodinger equation that we did in a review session today.

Ex. Beta-carotene is a conjugated polyene with delocalized electrons. This system can be treated as a particule in a box. If H= (h/8Π^2m)((d^2)/dx^2) write the schrodinger equation for this system.

We used the formula Hψ=Eψ and just plugged in the value for H given in the equation for H. That plugged in version of the equation was just our final answer. The person running the review session just told us to know the equation and what the variables in the equation stood for in case it shows up.

I think the keywords that hint at the Schrodinger equation are "particle in a box" or the mention of H or the Hamiltonian.
