		Rydberg then went on to produce another formula, which would express the frequency of every line in every series of an element.

		This fact was recognized in 1859 by the German scientists Gustav Robert Kirchhoff and Robert Wilhelm Bunsen.

		Johann Jacob Balmer analyzed the wavelengths of the lines created by a spectrum from a hydrogen atom.
		Later, Johannes Robert Rydberg found a formula that fit an even larger number of the atomic spectra lines for hydrogen.
		The importance of this is that Bohr connected flbody radiation, spectroscopy, and the theory of the atom: flbody radiation and spectroscopy are both caused by electrons moving between quantized energy levels.

		Rydberg Constant for hydrogen : Swedish physicist, Johannes Robert Rydberg (1854-1919) determined that if the numerical units of 109,737.31 per centimeter was used in simple equations as a constant factor the spectral wavelengths emitted by the element hydrogen from the deep infra red to the ultra violet could be calculated mathematically.
		Balmer Constant for hydrogen : German mathematician Johann Jakob Balmer (?- 1898) investigated a series of numbers representing the visible wavelengths of the lines of the hydrogen spectrum and found a formula that mathematically expressed the wavelengths of the lines.
		Because they were using the "hydrogen resonance frequency" to broadcast their messages they transmitted a number that definitely pertains to the spectral activity of the hydrogen atom which is known to us as the Rydberg Constant.

		The Rydberg electron is allowed to continue to absorb energy, so long as that energy is precisely of an amount that will propel the electron to the next trajectory allowed by the interference pattern.
		When Delos calculated the precise shape of the simple, classical orbit of the outermost electron that gave rise to the ripples seen in the Argonne experiments, he found himself back at the point where Bohr had abandoned his model in 1919: he was assigning definite trajectories to atomic electrons.
		To be sure, at low energies the orbits of Rydberg electrons are as simple and predictable as the ellipses of the Bohr model, but as the energy increases, and the motion becomes more agitated, classical chaos suddenly sets in.

		As a consequence, 'R' could be called the _Rydberg quantum wavelength_ since it is a specific fraction of the Rydberg* wavelength.
		Analysis of the terms making up the Rydberg constant indicate that such a dimensionless number can indeed be obtained provided one reasonable assumption is made.
		This Rydberg quantum number '_R_' then bears the value _R_ = (1182.4)p 4= 115176 Under these circumstances, the Rydberg quantum wavelength 'R' is defined as R = 1/(R_R_) = K/_R_ = 7.91197 ´ 10-11 centimetres It therefore follows that wavelengths increment in steps of D = _n_R* = _n_ (7.91197 x 10-11) centimetres.

		Due to their small binding energy, Rydberg states tend to be very fragile and sensitive to external perturbations such as collisions or electric fields.
		Rydberg atoms are so big that they are at the boundary that separates the quantum world from the classical world.
		Also note that the addition of energy causes the size of the atom to increase, just as it did in the case of the "nucleus" with nuclear isomers, except in this case the one-dimensional spin system cannot store the energy in a form that is as compact as a two-dimensional spin system.

	ATOMIC BEHAVIOUR AND THE REDSHIFT
		If we now follow the lead of Bohr, and quantise his second equation, a solution to several difficulties is found.
		As a consequence, 'R' could be called the Rydberg* quantum wavelength since it is a specific fraction of the Rydberg wavelength.
		This designated fraction is given by the dimensionless number 'R' which could perhaps be called the Rydberg quantum number.

		Thus the fledgling science of spectroscopy, which would develop into a vital tool for chemical analysis, was born.
