LYMAN SERIES - Hydrogen emission series in which electrons jump to the ground state. All of the lines are in the ultraviolet.
Lyman series
The series which describes the emission spectrum of hydrogen when electrons are jumping to the ground state. All of the lines are in the ultraviolet.
Lyman series: Spectral lines in the ultraviolet spectrum of hydrogen produced by transitions whose lowest orbit is the ground state.
Lyman Series - A series of absorption or emission lines of hydrogen lying in the ultraviolet part of the spectrum

Lyman Series
(a) A series of lines in the ultraviolet spectrum emitted by excited hydrogen atoms. They correspond to the atomic electrons falling into the lowest energy level and emitting energy as radiation.
Lyman series
In physics, the Lyman series is the series of transitions and resulting emission lines of the hydrogen atom as an electron goes from n = 2 to n = 1 ....

For the Lyman series the naming convention is:
n = 2 to n = 1 is called Lyman-alpha,
n = 3 to n = 1 is called Lyman-beta, etc.
Transitions down to (or up from) the ground state (level 1) from (or to) higher, excited levels form the Lyman series. The first is Lyman alpha (Ly), corresponding to the transition between the first excited state (level 2) and the ground state.
The wavelength () of the radiation in the Lyman series is given by 1/ = R(1/12 - 1/n2), where n is an integer and R is the Rydberg constant. see also Spectral Series [DC99] ...
These photons were from Lyman series transitions, putting them in the ultraviolet (UV) part of the electromagnetic spectrum.
This is shown schematically in the diagram below for the Bohr model of the atom. The Lyman Series involves transitions down to the n = 1 orbit and involve higher frequency photons in the UV region whilst the Paschen Series (to n = 3) produces IR ...
