Consider Potassium atoms in a flame atomizer. The 4s to 40transition has a spectral doublet at 766 nm. (nominal - average ofall 4p states)
- What is meant by the term "doublet" in the description, and whydoes this occur in potassium?
- Calculate the ratio of atoms in the 4p states (all three) tothose is the 4s state for a flame temperature of 2800K
- Potassium can be determined by flame-AES or flame-AAS, but thesignal in Flame-AES is very noisy. Explain why this is so and alsowhy ICP-AES acheives a less noisy signal.
