PDF | Flame emission spectroscopy is so named because of the use of a flame to provide the energy of excitation to atoms introduced into the flame. The energy distribution of the excited ejected atoms is shown to depend mainly on the electron configuration of the excited state. Some interference of sodium is corrected by a sodium-containing solution (140 mmol/L) for calibration. Both methods resemble the flame method of emission spectroscopy (i.e., a method that uses flame as the energy source to excite atoms) in that a solution of the sample is usually vaporized into a flame of hydrogen or acetylene in air or oxygen. 230 – 249 Problems: 9-1,3,5,6,8 .
