BET isotherm
--------------

The BET multilayer adsorption isotherm, its linearization for fitting
(Vm, C), and its numerical reduction to the Langmuir isotherm when
multilayer condensation is suppressed (P0 much larger than the working
pressure range).

    <div class="sphx-glr-thumbcontainer" tooltip="BETIsotherm generalizes Langmuir to multilayer adsorption. As the saturation vapor pressure P_0 \to \infty at fixed K=C/P_0, multilayer condensation is suppressed and BET reduces exactly to the Langmuir isotherm -- a reduction verified here numerically, not just asserted.">
