Input (English): Question: The deviation of Beer's law by the use of non-monochromatic radiation can lead to deviations from linearity when representing absorbance versus concentration due to: 
 Options:  <0> Different molar absorptivities of the absorbent species. <1> Very similar molar absorptivities of the radiations of the polychromatic beam. <2> That the radiant power of the incident beam is modified. <3> That the use of a polychromatic beam always implies significant differences with respect to a monochromatic one. <4> That the relation of incident and transmitted powers is different.
Output (English): pharmacology
