Question

In Atomic Absorption Spectrophotometry, narrow atomic lines are desirable. However, line broadening arises from: (a) Jablonski effect (b) Doppler effect (c) Plasma Effect (d) Background effect (e) Blue sky effect

Answer 1

Answer: b) Doppler Effect

Explanation:

Line broadening in AAS, arises due to some effects, which can occur due to a number of factors. The line width broadening effects include: Doppler, Lorentz, Self absorption, and quenching effects.

Doppler effect arises because along the line of observation, atoms will have different components of velocity.
