Spectral lines are lines which help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby. Sodium spectrum has bright doublet at and nm. This is said to be sodium D-lines.   the ratio of intensities of the D1 and D2 lines of Sodium at high temperature? 3/2), F can take any of the values 0, 1, 2, or 3, and for the D 1 excited state (3 2P 1/2), F is either 1 or 2. Again, the atomic energy levels are shifted according to the value of F. Because the fine structure splitting in sodium is large enough to be resolved by many lasers (∼ nm), the two D-line components are generally treated.   Sodium is a common element with a not-so-common effect on our lives. Most of us think of common table salt when we hear the word "sodium," but this book shows that it s much more than that! This lively book takes us through the discovery of sodium, and why it has its place on the periodic table. It then explores the atomic makeup of sodium, as well as how it Reviews: 1.

If you travel through some parts of your city, you will notice streetlamps that illuminate the street with a yellowish orange glow. This light is very particular; no matter where you go, if there is this kind of lamp, the colour will always be the. As showed in fig.1, the sodium 2 S ground state consists of two hyperfine substates separated by GHz splitting the D 2 line into the D 2 a and D 2 b transition pair, corresponding Author: Daniel A. Steck. In cool stars like the Sun, the sodium lines (a good spectrograph will show you it is a doublet, separated by nm, caused by LS coupling in sodium atoms) at nm is one of the most prominent absorption lines. Because stars like the Sun and cooler usually form the bulk of the light seen from a galaxy, this line is easily seen in galaxy. The Yerkes spectral classification, also called the MKK system from the authors' initials, is a system of stellar spectral classification introduced in by William Wilson Morgan, Philip C. Keenan, and Edith Kellman from Yerkes Observatory. This two-dimensional (temperature and luminosity) classification scheme is based on spectral lines sensitive to stellar temperature and .

The reason for the increase in the ratio of anti-Stokes to Stokes intensities with sample temperature is to be stated. Concept introduction: Raman spectrum consist two frequency emissions. The emission with lower frequency is called Stokes scattering (intensity or line) and with higher frequency is called anti-Stokes scattering (intensity or line). the Sodium doublet lines and the thickness of a Mylar film Separation of the sodium doublet lines Measurement of points of zero optical path difference For this part of the experiment the filter is removed from the apparatus and a sodium lamp is used as the light source for the Michelson interferometer.

An S-type star (or just S star) is a cool giant with approximately equal quantities of carbon and oxygen in its atmosphere. The class was originally defined in by Paul Merrill for stars with unusual absorption lines and molecular bands now known to be due to s-process bands of zirconium monoxide (ZrO) are a defining feature of the S stars.
