It is putting the light from the Sun or a star through a spectrograph, in other words a specially designed piece of equipment with a prism, to split it up into its different colours, red to violet.
A spectrosope uses collimated light so that each 'colour' or wavelength arrives in its own measureable position on the spectrum. When that is done, a set of dark lines can be seen in the spectrum, each line corresponding to an element or compound in the source that provided the light.
The sodium lines in the yellow part of the spectrum are a good example, and in the Sun's spectrum there are two dark lines close together in the yellow region, indicating that sodium is absorbing light in the outer layers of the Sun.
This technique is used to analyse stars in great detail to discover their chemical makeup.

Are there different types of raman spectroscopy?
Several variations of Raman spectroscopy have been developed.· Surface Enhanced Raman Spectroscopy (SERS)· Resonance Raman spectroscopy· Surface-Enhanced Resonance Raman Spectroscopy (SERRS)· Angle Resolved Raman Spectroscopy· Hyper Raman· Spontaneous Raman Spectroscopy (SRS)· Optical Tweezers Raman Spectroscopy (OTRS)· Stimulated Raman Spectroscopy· Spatially Offset Raman Spectroscopy (SORS)· Coherent anti-Stokes Raman spectroscopy (CARS)· Raman optical activity (ROA)· Transmission Raman· Inverse Raman spectroscopy.· Tip-Enhanced Raman Spectroscopy (TERS)· Surface plasmon polaritons enhanced Raman scattering (SPPERS)
How is fluorescence spectroscopy done?
Fluorescence spectroscopy is a type of spectroscopy that analyzes fluorescence from a provided sample. This uses a beam of light, often an ultraviolet light which then causes absorption spectroscopy to occur.
What are the three techniques for analysis of spectroscopy?
1 infra-red (UV-VIS) spectroscopy. 2 proton magnetic resonance spectroscopy. 3 carbon 13 magnetic resonoce spectroscopy.
