The absorption lines in the infrared portion of the spectrum of a star that are produced by hydrogen are from the Balmer series. The Balmer series were discovered by Johann Balmer in 1885.

The absorption lines in the infrared portion of the spectrum of a star produced by hydrogen are primarily the Paschen series. These lines are transitions of electrons in hydrogen atoms from higher energy levels to the third energy level (n=3). Typical Paschen series lines in the infrared include Paschen-alpha at 1.875 Ξm and Paschen-beta at 1.282 Ξm.

Does all molecules have infrared spectrum?
All molecules have an infrared spectrum.
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
Infrared spectroscopy analysis of unknown compounds?
Infrared spectroscopy is a powerful technique used to identify functional groups in unknown compounds by measuring the absorption of infrared light. By comparing the peaks in the infrared spectrum of an unknown compound to reference spectra, the functional groups present can be identified. This information can help in determining the molecular structure and composition of the compound.
How does infrared spectroscopy identify organic compounds?
Infrared spectroscopy identifies organic compounds by measuring the absorption of infrared radiation by the compound's functional groups. Each functional group absorbs infrared radiation at specific frequencies, which produce characteristic peaks in the IR spectrum. By comparing these peaks to reference spectra, the functional groups present in the compound can be identified.
How ir spectrum compound recorded?
An IR spectrum of a compound is recorded by passing infrared radiation through a sample of the compound and measuring the absorption of different wavelengths by the sample. The resulting spectrum displays peaks and troughs corresponding to different functional groups present in the compound, which provides information about its structure and composition.
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
Which absorption spectrum is equivalent to a fingerprint of a substance?
The UV-Vis absorption spectrum is often referred to as the fingerprint of a substance because it provides a unique pattern of absorption peaks and intensities that is specific to that substance. This spectrum is commonly used to identify and characterize unknown compounds in chemistry.
When is an absorption spectrum produced?
An absorption spectrum is produced when a substance absorbs specific wavelengths of light as it passes through it. This absorption results in the dark lines or bands seen in the spectrum, which can be used to identify the elements present in the substance.
Does all molecules have infrared spectrum?
All molecules have an infrared spectrum.
What is highest absorption to lowest. Highest Light Absorption?
The highest absorption in the electromagnetic spectrum includes gamma rays, X-rays, and ultraviolet light. Next comes visible light, followed by infrared, microwaves, and radio waves with the lowest absorption.
What is the wavelength of infrared for best water absorption?
The best wavelength for water absorption is around 3,000 to 3,500 nanometers in the near-infrared spectrum. Water molecules strongly absorb infrared radiation in this range due to the stretching and bending vibrations of the O-H bonds. This absorption is commonly used in remote sensing applications for water content detection.
How are infrared waves produced?
Infrared waves are produced when objects emit energy in the form of heat due to their temperature. This thermal energy causes the atoms and molecules in the object to vibrate, generating electromagnetic waves that fall within the infrared region of the electromagnetic spectrum.
How infrared wave produced?
by heat
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
What Is The Absorption Spectrum Of boron?
The absorption spectrum of boron typically shows strong absorption in the ultraviolet region, with some absorption in the visible spectrum as well. Boron's absorption spectrum is characterized by a series of sharp peaks due to transitions between energy levels in its atomic structure.
What meant by an absorption spectrum?
In the absorption spectrum the peaks are due to preferential absorption at a definite wavelength by molecules, ions, etc.
Do water absorb light?
Yes, water can absorb light, particularly in the near-infrared and infrared regions of the electromagnetic spectrum. This absorption of light energy can lead to warming of the water molecules and water bodies.
