Webpopulation: [noun] the whole number of people or inhabitants in a country or region. the total of individuals occupying an area or making up a whole. the total of particles at a particular energy level. WebFrom the handout energy level diagram, the transition wavelength is 3303 Å, so the excited state energy is: 1/ 2 2 1/ 2 42P →3 S J m hc Js ms E h 19 10 ... Since the intensity of the emission line is directly proportional to the population of the excited state, we can compare relative line intensities at the different temperatures directly.
