Collection of Useful Formulae and Constants:
Quantum Mechanics:
Schrodinger’s Time-Dependent Equation:
$ihbarfrac{partial}{partial t}left|Psi(t)right>=Hleft|Psi(t)right>$
Planck Constant:
$h =6.62606896(33) times 10^{-34}mbox{J}cdotmbox{s} = 4.135 667 33(10) times10^{-15}mbox{eV}cdotmbox{s}.$
Reduced Planck Constant:
$hbar equiv frac{h}{2pi} = 1.054 571 628(53)times10^{-34} mbox{J}cdotmbox{s} = 6.582 118 99(16) times10^{-16} mbox{eV}cdotmbox{s}$
