Fig. 4
Quadruple mass spectrometer temperature-programmed desorption curve (m/z 56) of a pure NH2CH2CN multilayered sample with a 2 K/min temperature ramp rate. The desorption rate was normalized to one-monolayer (1015 molecule cm-2) (dashed line). The solid line is the result of the fit by the zeroth-order Polanyi-Wigner equation.
