Paschen Series When an electron jumps from any of the higher states to the state with n = 3 (3rd state), the series of spectral lines emitted lies in near infra-red region and are called as Paschen Series. Their formulas are similar to Balmer’s except that the constant term is the reciprocal of the square of 1, 3, 4, or 5, instead of 2, and the… This series was observed by Friedrich Paschen during the years 1908. The key difference between Lyman and Balmer series is that Lyman series forms when an excited electron reaches the n=1 energy level whereas Balmer series forms when an excited electron reaches the n=2 energy level.. Lyman series and Balmer series are named after the scientists who found them.

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here! d) n 1 = 2, n 2 = 3, R H = 109677 cm-1. You can easily verify that if you replace $Z$ with $2Z$, then the energy of the corresponding transition will be four times the original energy. The lines can be calculated using the Balmer-Rydberg equation. Paschen series (n l =3) The series was first observed during the years 1908, by a German physicist Friedrich Paschen. Therefore the astrophysicist decides to check for hydrogen by looking at the Paschen series, which produces spectral lines in the infrared part of the spectrum. Paschen Series: If the transition of electron takes place from any higher orbit (principal quantum number = 4, 5, 6, …) to the third orbit (principal quantum number = 3).

What is the value of n high for this line. Colleagues don't congratulate me or cheer me on, when I do good work? You can plug in the Rydberg constant and the values n=4 and n=3 into the Rydberg equation to find the wavelength. For each series, assign the energy (infrared, ultraviolet, or visible), the nf value, and ALL possible ni values up to 7 (the order of ni values is not important). The following image shows the line spectra in the ultraviolet (Lyman series), visible (Balmer series) and various IR series that are described by the Rydberg equation. In spectral line series The Lyman series lies in the ultraviolet, whereas the Paschen, Brackett, and Pfund series lie in the infrared.

Now if you replace both $n_1$ and $n_2$ with $2n_1$ and $2n_2$, then you can take out a factor of $1/4$; so the transition $2n_1 \leftarrow 2n_2$ in an ion with nuclear charge $2Z$ occurs at the same energy/wavelength/wavenumber as the transition $n_1 \leftarrow n_2$ in an ion with nuclear charge $Z$. Same applies for any other factor $k$: the $1 \leftarrow 2$ transition in hydrogen occurs at the same wavelength as the $4 \leftarrow 8$ transition in $\ce{Be^3+}$.
