why pure rotational spectrum is almost always seen as absorption lines,and not as emission lines?
there exists both spectra absorption and emission butkoustav said:why pure rotational spectrum is almost always seen as absorption lines,and not as emission lines?
That's probably because people are most likely to look into the absorption lines.koustav said:why pure rotational spectrum is almost always seen as absorption lines,and not as emission lines
Rotational spectroscopy is a branch of spectroscopy that studies the absorption or emission of electromagnetic radiation by molecules due to their rotational energy levels.
This is because rotational transitions in molecules typically involve a change in the rotational energy levels from a lower to a higher state, which results in the absorption of radiation rather than emission.
Rotational spectroscopy is used to identify and study the structure and composition of molecules in various fields such as chemistry, physics, and astronomy. It can also be used to measure physical properties of molecules, such as bond lengths and dipole moments.
Rotational spectroscopy can be used to study any molecule that has a permanent electric dipole moment, which includes most molecules composed of two or more atoms. It is particularly useful for studying small and simple molecules.
Unlike other types of spectroscopy, such as infrared or ultraviolet spectroscopy, rotational spectroscopy specifically focuses on the rotational energy levels of molecules. It is also a highly accurate and precise method for measuring molecular properties, making it particularly useful in analytical chemistry.
