This equation is simply an application of eq. 8.39 to a 2-state system. C1 and C2 are the components of the wave function along each of the 2 basis states. H12 and H21 are the off-diagonal terms in the Hamiltonian.


[tex]

\mathcal{H} \equiv \left(
\begin{array}{cc}
H_{11} & H_{12}\\
H_{21} & H_{22}
\end{array}
\right)

[/tex]
