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.
All molecules have an infrared spectrum.
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.

No, its an absorption spectrum
When light from a hot solid or dense gas passes through a cooler gas.
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
infrared ray from electromagnetic spectrum can creat heat directly ,heat is generated when photons are interact with matter. Due to vibration of molecules and electrons heat is generated.
In the absorption spectrum the peaks are due to preferential absorption at a definite wavelength by molecules, ions, etc.
