Answer:
The intensity of a spectral line at a given frequency is related to the net rate of absorption (or emission) at that frequency. ... The more intense the incident radiation, the greater the rate at which transitions are induced to the higher state and thus the stronger the absorbance of the sample.

According to XI (1.17) the intensity of spectral lines is determined by the effect operator for the emission of a photon of frequency ω nm as follows:
