The first excited state of Ca2+ is assed with 422.7 nm light. The degeneracy ratio g*/g0 =3

a ) Use the Boltzmann distribution to calculate the relative population of Ca in the ground and the excited state ie the ration N*/No at

(i)             2500k                         (ii)       6000k   

(b) A student wishes to collect a florescence emission spectrum. They are using the narrow slits for the excitation monochrometer and broad slits for the emission monochrometer. Explain why that is counter-productive?
