Alkali spectra. ?Doublet structure of Alkali spectra: Careful examination of the spectra of alkali metals shows that each member of some of the series are closed doublets. For example, sodium yellow line, corresponding to 3. 3 p s. > transition, is a close doublet with separation of 6A. 0 while potassium (K) has a doublet
Lecture 10 : Title : ALKALI SPECTRA. Page-0. In the previous lecture we have learnt the quantum mechanical treatment of hydrogen atom. The similar picture is not able to explain the alkali atoms, the other elements in the first group of periodic table. Here, we will discuss the development of the theory to explain the alkali
1 Mar 1987 Emission spectra of quasimetastable levels of alkali-metal atoms. A. J. Mendelsohn,' C. P. I. Barty, M. H. Sher, J. F. Young, and S. E. Harris. Edward L. Ginzton Laboratory, Stanford University, Stanford, California 94305. (Received 30 September 1985; revised manuscript received 7 November 1986).
Emission spectra of alkali atoms has been determined by using spectrometer at the ultraviolet to infra red waves range. The spectra emission can be obtained by absorption spectrophotometric analysis. Comparative evaluations between experimental data and data handbo.

In this module, you will study about the failures of the Bohr theory, which led to the formulation of the quantum theory. You will understand how the new theory could explain the fine structure in the spectra of hydrogen and hydrogen-like ions, and how this theory can be extended to atoms which have a single electron in their

PY3P05 o Alkali atoms: in ground state, contain a set of completely filled subshells with a single valence electron in the next s subshell. o Electrons in p subshells are not excited in any low-energy processes. s electron is the single optically active electron and core of filled subshells can be ignored. PY3P05 o In alkali atoms,
Atomic structure and spectra. 2.1 Atomic structure. 2.1.1 The hydrogen atom and one-electron atoms. The Hamiltonian for one-electron atoms such as H, He+, Li2+, , can be written as. ?H = ?p2. 2me. ?. Ze2. 4??0r. ,. (2.1) where ?p is the momentum operator, me is the electron mass (me = 9.10938291(40) ?. 10. ?31 kg), Z is
n+10 ) pro- duced in a supersonic jet are doped with alkali atoms. (Li,Na,K) and characterized by means of laser induced fluorescence. Each cluster contains, on average, less than one dopant atom. Both excitation and emission spectra have been recorded. The observed excitation spectra are analyzed, calculating the
