Zinc is detected using the absorption/emission wavelength of 213.9 nm. a. Convert this wavelength to energy in Joules. (3 pts) b. Given that this transition has relative degeneracies, g*/go, of 3, calculate the distribution in the excited state versus the ground state, N*/No, at 2600 K (the average temperature of an acetylene/air flame) and 3000 K (the average temperature of an acetyleneitrous oxide flame). k = 1.381 x 10-23 J/K (8 pts) c. Based on your results in b, how feasible is atomic absorption spectroscopy of zinc at 213.9 nm using an acetylene/air flame and an acetylene nitrous oxide flame? (3 pts) d. Based on your results in b, how feasible is atomic emission spectroscopy of zinc at 213.9 nm using an acetylene/air flame and an acetylene nitrous oxide flame? (3 pts) e. An inductively coupled plasma torch operates at an average temperature of 8000K. Calculate the distribution in the excited state versus the ground state, N*/No, at 8000 K. (4 pts) f. Which of the atomic spectroscopy techniques would you expect to be improved by the use of an ICP atomization source? (3 pts)
